In short: Aloysius Xingu Leng Pendergast is an enigmatic FBI special agent known for his intellect, Southern manners, and mastery of disguise. Raised in New Orleans, he navigates the world of high-stakes investigation while grappling with a family history defined by insanity, patent medicine fraud, and a legacy of gruesome crimes.

Born in December 1960, Pendergast is a highly educated polyglot who holds two D. Phil. degrees from Balliol College, Oxford, and studied anthropology at Harvard. His professional life as an FBI agent is marked by his ability to manipulate bureaucrats and his expertise in forensic science. Despite his refined tastes—favoring Château Pétrus wine and steak tartare—he is a man of contradictions, often carrying hidden tools like lock picks and syringes while maintaining a zen garden in his New York City apartment.

His personal life is deeply intertwined with his family's troubled past. The Pendergast fortune, once thought to be legitimate pharmaceutical wealth, was actually built on 'Hezekiah's Compound Elixir and Glandular Restorative,' a lethal tonic sold by his great-great-grandfather that caused numerous deaths. This history of moral decay is mirrored by a recurring streak of insanity within the family, leading many ancestors to commit heinous crimes. His great-granduncle, Enoch Leng, was a serial killer who pursued life-extending elixirs, while his brother, Diogenes, became a murderous antagonist in the 'Diogenes Trilogy.'

Pendergast’s inner circle includes his ward, Constance Greene, an anachronism born in 1876 who was raised by Enoch Leng, and his loyal assistant, Proctor, a former member of the elite Special Forces 'Ghost Company.' Pendergast himself served in this same unit, which held the motto 'Fidelitas usque ad mortem.' Today, he resides in a Beaux Arts mansion on Riverside Drive, a property once owned by his ancestor, where he continues to balance his scientific rigor with the shadows of his lineage.
