From the Edgar® Award winning author of Uneasy Relations. Starring Professor Gideon Oliver? ?a likable, down-to-earth, cerebral sleuth.? (CHICAGO TRIBUNE)
Sailing the Amazon with a group of botanists, ?Skeleton Detective? Gideon Oliver is on his dream vacation. But it turns nightmarish when fierce head-hunters narrowly miss killing the group leader, then a deranged passenger kills a botanist and flees. Long-past enmities and resentments?and new ones as well?might explain things. And when a fresh skeleton turns up in the river, Gideon is sure that, in this jungle full of predators, humans may be the deadliest of all.

Aaron Elkins is the author of the Edgar Award-winning Gideon Oliver mysteries.
