My grandfather used to make little riddles when I was little and I'd have to solve the riddle to find things he'd hidden around the house, one riddle read "I’m being held by two hands with no fingers in sight" I searched for ages and I loved it, eventually I got another clue "I have a face with only numbers" and it clicked, the grandfather clock wasn't ticking, he had stopped it and slot a £5 note in between the hands. The joy of finding his gifts was always magical, I wanted to make another perfect hiding spot. So I did.
