Titre original : Man In a Trench Coat
On a dark night when Steve is away, Robbie and his date are frightened by a man in a trench coat. It all happens when Robbie is seen putting on the hubcap of his next door neighbour. Steve isn't too concerned when he hears about the incident as he thinks it all stems from Robbie's steady diet of spy and mystery stories.
