Special Agent Aloysius Pendergast appears in four stand-alone novels in addition to starring in his own trilogy. All of these books were jointly written by Douglas Preston and Lincoln Child.
- Relic (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 reporter Bill Smithback and Vincent D'Agosta. (I'm 80% done with this book)
- Reliquary -- 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.
- Cabinet of Curiosities -- Pendergast is drawn to the remains of a 19th century charnal house, unearthed at a construction site in New York and finds himself investigating a new series of copycat killings. He is joined by William Smithback Jr. and Dr. Nora Kelly. (I've read this before but love it so much I'm going to read it again in order).
- Still Life With Crows -- Agent 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 teenage malcontent, Corrie Swanson to solve the case. (I'm about 30% through this one).
Brimstone (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 (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 author's non-Pendergast novels.
