Nero Wolfe 09 - Black Orchids

Not much can get Wolfe to leave his comfortable brownstone, but the showing of a rare black orchid lures him to a flower show. Unfortunately, the much-anticipated event is soon overshadowed by a murder as daring as it is sudden. It's a case of weeding out a cunning killer who can turn up anywhere--and Wolfe must do it quickly. Because a second case awaits his urgent attention: a society widow on a mailing list of poison-pen letters leading to a plot as dark as any orchid Wolfe has ever encountered.
