Gretchen Falk has everything a Park Avenue socialite could want: wealth, status, and a devoted husband Richard who fathers their three children. She begged him not to join his college friends on their Mount Kilimanjaro expedition, sensing danger in the distance. Her instincts prove correct, but the threat comes from an unexpected source. Frankie Callahan climbs the mountain to celebrate her upcoming gallery exhibition and escape a troubled past. She expects solitude among the male climbers but finds herself drawn to the charismatic, married Richard. The group descends one person short of their original number. Two weeks later, Frankie lies dead in her blood-soaked East Village apartment. Police arrest Richard for murder. Gretchen faces the wreckage of her carefully constructed life, clinging to two certainties: Richard loves only her, and he could never kill anyone. She must discover how a mountain expedition destroyed everything she held sacred.
