Nero Wolfe, lover of fine food and prize orchids, is a genius at daring detection. But he is always on guard when it comes to women. Now murder at a fencing studio engages him and his confidential assistant, Archie Goodwin, in a dangerous duel with death. The prime suspect is a Balkan beauty who has a secret reason for wanting Wolfe to clear her — and a double identity that may be the perfect foil for covering up a killer.
