Desiree, Guz and Morgana solve the riddle
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Morgana immediately got Desiree to say the word 'submarine'. After dressing as Charlie Chaplin, Desiree became increasingly frustrated by Guz who kept saying he had a revelation, although he only found the riddle after 41 minutes. Morgana ended up suggesting Desiree and Guz stand in their doorways so they could both see the map and Desiree could find her jigsaw as Guz didn't think he could describe it. After an hour has passed and Guz struggled to tell Desiree and Morgana what the letters on the back of his jigsaw meant, Desiree requested Alex retrieve Guz's jigsaw so Desiree had a complete puzzle. Whilst she deciphered the riddle, Guz found a guitar and started singing about how much he hated the task. Desiree eventually deciphered the riddle and solved it herself. They solved the riddle in 1 hour and 33 minutes, receiving 2 points each. Morgana received a bonus 2 points for getting Desiree to say the word "submarine".
