Promising blend of hard-boiled crime flick and campy detective yarn that doesn't quite go the distance. Pulpy plot features a gaggle of cartoony characters and Frank Sinatra at his wiseass best playing Florida private dick wrapped up in convoluted mystery centering on millionaire's daughter (Sue Lyon). Terrific supporting cast includes Gena Rowlands (looking lovely), Jill St. John (at her slinky, sexy best), Simon Oakland and Richard Conte, but the plot runs out of gas somewhere in the second act. A bit stronger than its immediate sequel, "Lady in Cement", and Sinatra's panache is definitely worth checking out. After getting out of a rickety elevator, he tells the female operator, "Nice riiide." **1/2 from ****
