Karl and the Missing Slippers

Karl liked slippers alot. There is nothing like it, after a hard day deciding what the wealthy should wear next season, to slip ones tired feet into a pair of giant monkey slippers. Naturally Karl had an assistant to organise his slippers. This highly coveted post was only open to applicants after seven years working as his underpants assistant. When news of a vacancy was announced there was great excitement in Paris.
A queue formed around the block on the day of the interviews. Unknown to Karl, John from Dior was cunningly disguised in the queue as a chimney sweep and had mischievous plans afoot.
That night poor Karl discovered a space where his favourite slippers, should be. In its place was a strip of unfinished knitting, white acrylic, feather and fan stitch. The yarn end trailed away, with a note instructing the finder to follow the trail to find the slippers. Unfortunately the trail ran cold when it emerged some tidy person had seen the strand , and thinking it waste, cut it, and binned it. Karl never found his favourite slippers.
