Strangled by hand, Sydney Bell's murder has a peculiar look to Jeremiah Gibson, Asst. D.A. of N.Y. County, who, with his sidekick Mac, tries to tie in the disappearance of her glamorous wardrobe with the prim, sparse one left in her apartment. Her most moral brother and his equally righteous fiancee, a wild playboy from Conn. and his hard- cash followers and four more killings take Gibby through the works. Medium done.
