Katherine and Mawaan find the treasure, while Johnny makes noises

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Katherine and Mawaan managed to find the pin-hole camera immediately, discovering the message in the briefcase. After checking the sinks in the house, they realised it was in the caravan, using a blowtorch to melt the camera and retrieve the key. They found the treasure in 17 minutes and 34 seconds. Johnny made random noises every minute including: Richard Nixon's "I'm not a crook", a typewriter, a chimpanzee, mooing, and an engine.
