Amy pointed to the photographs. "Look at that scene. It tells you right there who the killer is."

Her father frowned. "How do you figure?"

"All right," Amy said, folding her arms. "The story begins with the poor old widow having guests in for tea. That pipe-smoking professor sees a figurine on her mantle: "An Egyptian funerary statue. Matilda, it's priceless."

Harry remembered. "Old Matilda is amazed by her good luck, and the three guests watch as she wraps the little statue in a handkerchief and buries it in the coal scuttle for safekeeping."

"The professor, the society girl and the old doctor," Amy added, pointing to their pictures. "The fourth suspect, Matilda's playboy nephew, arrives later, completely drunk. He doesn't even come inside but falls asleep in his car.

"Later that night, the shadowy killer, wearing gloves, sneaks into the old lady's cottage. The widow hears a noise and sits up in bed. She gets up and wanders into the drawing room. 'Hello? Who's there?' And bam - she suddenly gets stabbed in the back.

"The next morning, they're all in the village square, within shouting distance of the cottage, when the nephew knocks on the door. Aunt Matilda doesn't answer, so he pushes it open. He sees the body, shouts 'murder' and the others come running in. And this is the moment - all of them discovering the murdered woman together."
