The third mini-mystery for elderly scholar Sister Mary Teresa (a.k.a. ""Emtee"" Dempsey), a Chicago nun who plays the cool, wise Nero Wolfe role--with two far younger sisters as her peripatetic Archie Goodwins. The puzzle starts with a visit to the shabby nuns' house from Sister M.T.'s former student Diana Torrance--who spills a tale of woe about her unfaithful hubby Phil, the ""George Steinbrenner of women's soccer."" Almost immediately thereafter, Phil is found dead in Belmont Harbor, apparently knocked off his boat--with Diana (whose alibi is fishy) the prime suspect. Sister M.T. knows better, of course, dispatching casually dressed Kim to interview an array of suspects: Phil's soccer-star girlfriend (who herself is victim #2, with a drug overdose); Phil's unhappy business partners; the soccer star's agent. And finally comes the full-cast gathering, with Sister M.T. recapping and fingering the culprit. Thin, obvious plotting--but there's charm in the Sister's Wolfe/Marple act, plus pleasant Chicago/Vatican II chatter.
