Little Tiny Teeth

Forensics anthropologist Gideon Oliver's compelling 14th adventure (after 2006's Unnatural Selection ) involves a hot, humid and decidedly deadly expedition up the Amazon River with his friends Phil Boyajian, who heads a budget travel agency, and FBI agent John Lau. While Phil rates the boat's amenities, Gideon and John marvel at the natural wonders. But before long, they pick up on tension among the other passengers, who include world-famous ethnobotanist Arden Scofield and two of his colleagues—a ghostwriter and a bug researcher—plus a mysterious guide known only as Cisco. As the travelers go deep into the jungle, fearful of the rarely seen Chayacuro headhunters, Gideon and his pals find themselves in the middle of a decades-old blood feud, along with drug smuggling, greed and murder. Edgar-winner Elkins delivers fascinating descriptions of the Amazon and a satisfying denouement, courtesy of Gideon's characteristically astute analysis of human remains. (June)
