A phone call from an exotic woman gets Archie Goodwin’s attention, but when a gunshot sounds, it turns into the next case for Nero Wolfe. Going to the scene, Archie finds the body, and her date who she was to meet. Back in the office, Nero reviews the details of the crime, and interviews the pilot who Archie found in her hotel. Is it a suicide, a murder? At least, its time to get the cops involved.
Due to his diligent investigation, Archie has turned up more contacts the dead woman was to have made. Ellen was to purchase medical equipment to have shipped back to her home country. Was she killed over something she bought? More characters, Mr Renfro, and Miss Bennet, have their chance to be interviewed by Nero. Is their involvement in the large medical purchases legitimate?
Danger looms for Archie as he finds surprises, and a thump on the head. By now, Nero has enough to figure it out, and the players are rounded up for the big reveal in his office.
