Tiger in the Smoke

Having been sent a picture of her husband, a war hero killed in France, Meg Elgin is led to believe he is still alive and arranges a meeting at a London railway station. When she arrives there with the police accompanying her, she catches sight of a man in the distance wearing an old coat (clothing) of her husband's. When he is pursued and captured, he turns out to be Duds Morrison, a former soldier and out-of-work actor recently let out of prison. He refuses to tell them anything, and having nothing they can charge him with, the police release him.
