Just then a van pulled up outside Mark's house.
Four uniformed Police Officers and a spaniel dog with the waggiest of tales marched up the path.

Breaking the door down, the dog was let loose. Mark was told to 'Stand exactly where you are' and did so.
The spaniel sniffed around, then headed in the direction of the kitchen. Suddenly the dog raced to the vegetable rack, barking excitedly.
Immediately, the dog's handler ran to his dog's side. Looking in the vegetable rack, he saw a collection of mushrooms. Carefully he picked one up, examined it, then put all the mushrooms in a bag.
'You are under arrest' said one of the other officers, 'for the possession of suspect mushrooms.'

Mark was ushered into the waiting Police car which had also arrived.

Despite his protestations, he was found guilty of possessing illegal substances and sentenced to a long term of imprisonment.
