In a large estate, amiddle aged man relaxes in his library. Suddenly, there’s a break in, and he is stabbed. The man’s tearful daughter Laura goes to Mr Keen the next day to ask for his help. He was a kind, and generous man. Who would have a reason to kill him?
Police have determined the killer broke into the house through a window while Laura was sleeping upstairs. She is suddenly inspired with a thought that it may be a matter of her jealous, jilted boyfriend, George. Laura has just been engaged to Charles, and George thinks it’s all her father’s doing. Making her dump him because he’s poor, and pushing her off on Charles because he’s from a well off family. Mr Keen assures Laura that he’ll do all that is within his power to solve the mystery, but warns her that her life may be subjected to danger.
First Mr Keen and Mike visit the scene of the crime. The window had been locked, and seems to be the reason why the killer had to break the glass. With all the blood, I bet the killer will have a bandaged hand.
Mr Keen eavesdrops on a phone call between Laura and a friend, and suspects the conversation that implies George is too convenient, and George may be getting set up in a trap. As Mike investigates outside with Laura, Mr Keen pokes around indoors. George is on the premises with his bandaged hand, and Mike finds an extra clue when he catches up to George. He claims that he came to tell Laura it wasn’t him, and tells how he cut his hand. Is he telling the truth?
Just then the fiancee arrives to keep an eye on George while Mr Keen goes out to examine the dead rabit that Mike found. The hole in the ground is there, but the rabbit is gone. Another intruder is on the grounds, a young lady. A new rift is exposed between Laura and the woman who was in line with marrying her dad.
Inside there’s a struggle, apparently the fiancee tried to clobber the handcuffed, and defenseless George. Besides that, Mr Keen has already figured it out, and this only provides more evidence to rake the real killer over the coals. The desperate killer breaks down, gets violent, and admits to his past life of crime.
What was it that put Mr Keen on to him? What does the rabbit have to do with anything? Listen to see what the mystery is about, and the elaborate plan for a murder and a set up.
