Dead Men's Hearts

Anthropology professor, bone expert and renowned ``Skeleton Detective,'' Gideon Oliver makes his eighth appearance, following Make No Bones , in Edgar-winning Elkins's engaging, mainly cozy, series. Not even the idiosyncratic Gideon and his wealth of appealing bone lore can, however, redeem the narrative's uncharacteristically sluggish pace. At Horizon House, a research facility in Luxor, the remains of a previously catalogued, 4400-year-old skeleton are found, mysteriously out of place in a storeroom. Gideon, who is there adding color commentary to a documentary dealing with ancient treasure, takes a look at the bones, at the same time noting the feuding among unwieldy academic egos and sorely harassed support staff. The suspicious death of the much disliked Horizon House director, who had accompanied the filming crew on a Nile riverboat, intensifies the mystery, especially after more bones--too many--with the same catalogue number turn up. Gideon remains charming and eccentric, especially with a dusty bone in hand or his beloved wife Julie nearby, but the conclusion, lacking the kind of after-the-fact inevitability relished by mystery lovers, mildly disappoints.
