Quick recap
Former actress Margaret McGinty is found hanged, and her lodger goes on trial. Miss Marple, the lone juror who doubts his guilt, hangs the jury and starts digging on her own. The trail leads to H. Driffold Cosgood's theater company, which Marple joins as an actress. She learns McGinty was blackmailing someone in the troupe. One actor is poisoned, and an actress dies in an attempt meant for Marple. The killer is Bill Hanson, whom McGinty raised as a boy after his mother was executed for killing her husband. Engaged to an heiress, he killed to bury his past. In the end, Cosgood asks Marple to fund a play, and she says no.
