A detective's search for a missing friend "careens ahead with the speed and promise of danger of the Indy 500" (The Washington Post Book World).   With a genius IQ, a past career as a circus acrobat, and a black belt in karate, criminology professor Dr. Robert Frederickson--better known as "Mongo the Magnificent"--has a decidedly unusual background for a private investigator. He also just so happens to be a dwarf.   Mongo's friend and sensei, Veil Kendry, is pretty magnificent himself. A devoted martial arts instructor and extremely successful abstract artist, Veil single-handedly transformed his shady neighborhood in New York City's Lower East Side into a safe haven from crime and corruption. But when Mongo enters Veil's abandoned apartment and finds a bullet hole, a cryptic oil painting, and an envelope addressed to him containing $10,000, he starts to worry that Veil's reputation as a vigilante has gotten him into the worst sort of trouble.   Determined to find his friend, Mongo attempts to rule out any enemies from Veil's past--details of which Veil has never shared with him. But as he uncovers the shocking truth of Veil's time in the Vietnam War--participating in dangerous CIA missions under the call sign "Archangel"--Mongo soon finds enemies aplenty, ones that will do anything to make sure the past remains a secret . . .   In addition to creating "the most engaging detective in decades," author George C. Chesbro introduces the character of Veil Kendry, who would go on to have his own series (Library Journal).   Two Songs This Archangel Sings is the 5th book in the Mongo Mysteries, but you may enjoy reading the series in any order.
