The Last Coincidence

Description for THE LAST COINCIDENCE by Robert Goldsborough:

Playboy Sparky Linville has a nasty notion of fun and games. But when he picks popular Noreen James as his unwilling playmate, the result is murder - and a case that rocks Manhattan's trendy Upper East Side and divides the family of Lily Rowan, Noreen's aunt. At a loss, Lily turns to dear friend Archie Goodwin, who conveys the whole Nero Wolfe. It takes some coaxing - and the promise of a sizable fee - to distract the sedentary supersleuth from his greenhouse and groaning board. Yet once undertaken, this case fast becomes the most fascinating of his career, as the great detective is left to ponder a killer of a coincidence.

This is #4 in A Nero Wolfe Mystery.
