The grimy cafe down by the docks is keeping pretty busy as usual. The juke-box is giving out the latest sounds of the Mersey Beat at full volume; the youngsters are sitting around drinking strong tea out of thick mugs. But there is one customer at McKinley's who doesn't seem to fit in. That is Brayne, the old tramp. He has no money for tea, but he is wearing an expensive overcoat and a business gent's bowler hat. Smith and Weir get really involved when they try to find the reason.
