No, the ancient Egypt theme is just part of the book. As with all of them, it's really all about the museum. It's definitely a "cursed artifacts and relics type of thing".

Just fictional characters within the series, but it's become a long-running (multiple book) story arc that involves the two of them. Diogenes is Agent Pendergast's sociopathic brother. There you go. Nutshelled, free of charge.

No problem!

Aloysius X. L. Pendergast is a fictional character appearing in novels by Douglas Preston and Lincoln Child.

In the novels, Pendergast is a special agent with the United States Federal Bureau of Investigation (FBI). He is a favorite among fans for his unique personality, appreciation of culture and his almost supernatural competence. He works out of the New Orleans, Louisiana branch of the FBI, but frequently travels out of state to investigate cases which interest him, namely those appearing to be the work of serial killers.

Born to a wealthy Southern family of French and Creole descent circa 1960 and raised in New Orleans, Pendergast retains his gentlemanly Southern manners and mellifluous Southern accent. He studied Anthropology at Harvard University (graduating summa cum laude) and received a dual D.Phil. in Classics and Philosophy from the University of Oxford. As mentioned in Relic, Pendergast served with the U.S. Special Forces. One rumor said of Pendergast's Special Forces service was he had walked out of "a Cambodian death camp" as the lone survivor, but at the height of the Vietnam War and SF operations in Cambodia he would have been in elementary school. At some point during his lifetime, Pendergast married, but has indicated that he is now a widower. Very little is known about his late wife, other than that she was a skilled big game hunter and may have died only a few years before the events of Relic.

Pendergast is a withdrawn man, but can be remarkably polite, charming or dangerous when need be. Well-learned in many subjects, he converses easily with doctors, scientists, and intellectuals. He is a master of manipulation, both of people and of his own mind when difficult circumstances demand a fresh view of the situation.

Appearance
Pendergast's build is described as tall and thin, and he boasts a strong torso with lean muscle. His fingers are long and tapered. Pendergast has silver-colored eyes, a pale complexion, and light blond hair that appears almost white. He has been described as an albino. Pendergast typically dresses in a black, hand-tailored, designer suit regardless of weather conditions, and is often described as looking like a well-dressed undertaker. Observers note that he moves with a "Cat-like" grace. His demeanor is quiet, even taken aback.

In many cases, Pendergast's normal appearance is irrelevant. A master of disguises, he has fooled even close acquaintances on several occasions.


Accoutrements
Pendergast owns and drives a 1959 Rolls-Royce Silver Wraith. His personal sidearm is usually a M1911A1 .45 caliber pistol that is expensive or customized, and usually both. In The Cabinet of Curiosities, Still Life with Crows and The Wheel of Darkness, it is a Les Baer .45 caliber Government Model. He has also mentioned a "Signature Grade" by Florida SWAT trainer and gunsmith Hilton Yam in his collection that has not been seen outside a hypnotherapy session. During the climactic scene in "The Book of the Dead", he carries the more common Colt-produced version.

An internally-renovated Beaux Arts mansion on 891 Riverside Drive in New York City, near Harlem, and inherited from a deceased relative in The Cabinet of Curiosities, serves as his personal residence. Pendergast also has an apartment at the Dakota.

Normally kept hidden from view, Pendergast wears a chain with a pendant that depicts a lidless eye over two moons, one new and one full, and a phoenix. The Pendergast family crest consists of the same eye and moons, but a lion instead.

Pendergast carries a variety of hidden tools, such as lock picks, flashlights of various sizes, test tubes, syringes, and forensic chemicals.

Interests
Pendergast appreciates the finer things in life, including expensive cuisine and wines. He has a stock of 1990 Petrus, and one of his favorite drinks is green tea. He is known to enjoy steak tartare. He also has a passion for Bonsai trees. He enjoys classical music but detests opera. Pendergast has displayed sufficient ability in unarmed combat (see Brimstone) to kill a prison inmate with his bare hands (see The Book of the Dead). He has spent considerable time studying deep meditative practices known as Chongg Ran.

Pendergast is a student of many languages. He is fluent in Italian, Latin, Greek, and Chinese (some Mandarin, fluent in Cantonese). He does not speak German or Neapolitan.

Chronicles
Special Agent Aloysius Pendergast appears in five stand-alone novels in addition to starring in his own trilogy. Although, they are intended to be stand alone novels, they all in there own little ways connect through, small mentioning of previous books, characters, and events. All of these books were jointly written by Douglas Preston and Lincoln Child.

Relic (1995) (Pendergast's First Appearance) — Pendergast investigates a series of strange murders and rumors of a murderous beast in the New York Museum of Natural History. Includes Margo Green, reporter Bill Smithback and Vincent D'Agosta.

Reliquary (1997) — Pendergast returns to New York when a new string of murders surfaces resembling those of the Museum Beast case. He is again teamed with Margo Green, Dr. Frock, William Smithback Jr., and Vincent D'Agosta (all of whom were in the previous book) and introduces the character of Laura Hayward.

The Cabinet of Curiosities (2002) — Pendergast is drawn to the remains of a 19th century charnel house, unearthed at a construction site in New York and finds himself investigating a new series of 20th century copycat killings. He is joined by William Smithback Jr. and Dr. Nora Kelly.

Still Life with Crows (2003) — Pendergast travels to midwestern Kansas to the dying farm town of Medicine Creek to investigate a series of brutal and ritualistic killings. He teams up with a teenage malcontent, Corrie Swanson, to solve the case.

The Wheel of Darkness (2007) — Pendergast has taken Constance on a whirlwind Grand Tour, hoping to give her closure and a sense of the world that she's missed. They head to Tibet, where Pendergast intensively trained in martial arts and spiritual studies. At a remote monastery, they learn that a rare and dangerous artifact the monks have been guarding for generations has been mysteriously stolen. Pendergast agrees to take up the search. The trail leads him and Constance to the maiden voyage of the Brittania, the world's largest and most luxurious passenger liner—and to an Atlantic crossing fraught with terror. (Note: This story takes place chronologically after The Book of the Dead, and ideally should be read only after reading the entire "Diogenes Trilogy," but is a stand-alone novel.)

Revenant (Working Title) (2008) — Pendergast returns to NYC in New York Times bestselling authors Douglas Preston and Lincoln Child's newest novel featuring the enigmatic FBI Special Agent Aloysius Pendergast. William Smithback, a NY Times reporter, and his wife Nora Kelly, a Museum of Natural History archeologist, are found brutally attacked in their apartment on the Upper West side of Manhattan. Eyewitnesses claim and the security camera confirms the killer seen leaving the building was the strange, sinister man who had previously occupied Smithback and Kelly's apartment—and who had died horribly in it exactly one year ago. Captain Hayward leads the official homocide investigation, while Pendergast and D'Agosta undertake a private quest for the truth. Their serpentine journey takes them into a part of Manhattan they never imagined could exist: a secretive and deadly hotbed of Obeah, the West Indian Zombii cult of sorcery and magic. And it is here they find their true peril is just beginning.

The Diogenes Trilogy
Brimstone (2004) (Book One) — Agent Pendergast and Vincent D'Agosta team up once more to investigate brutal murders of a seemingly supernatural origin. Their investigation takes them from high society New York to old world Italy and into the dark heart of an age-old conspiracy. Vincent D'Agosta, Laura Hayward and Bill Smithback's nemesis, reporter Bryce Harriman (mentioned often in the previous books) make a reappearance. In this book the reader is introduced to Pendergast's brother Diogenes and D'Agosta catches his first glimpse of Diogenes.

Dance of Death (2005) (Book Two) — Aloysius Pendergast faces off against Diogenes in an attempt to stop his diabolical brother before he can complete the perfect crime. All of Pendergast's old compatriots find themselves in danger and old friends band together in the race to prevent an almost certain disaster. The novel features an all-star cast for Preston-Child fans and includes cameos from all of the books even going so far as to include characters from the authors' non-Pendergast novels. The book also hints at a sequel to The Ice Limit.

The Book of the Dead (2006) (Book Three) — The final book of the Diogenes Trilogy. The Book of the Dead picks up immediately following the conclusion of Dance of Death, with Diogenes Pendergast continuing his work towards the completion of his master crime. The majority of the action centers around the opening of the long closed (and cursed?) Tomb of Senef at the New York Museum of Natural History. The pursuers become the pursued, and the novel builds to a thrilling conclusion.

In the film version of Relic, Agent Pendergast is absent.

Cabinet was creeping and Still Life was fast paced and not so creeping. I think we will see Corrie Swanson show up in future Preston/Child "children" so to speak to be another of their creations to sort out all evil.

Which actor do you see playing Agent Pendergast in some sort of Hollywood production. I see Paul Bettany (Silas, in The Da Vinci Code), or Ralph Fiennes.

I also hear that both Child and Preston are good writers on their own as well. Any opions on that?
