Opportunity Knocks and Bruises

Arthur sells some surplus stock to Nolan, a fairground owner, in exchange for a slot machine, but discovers that the machine is full of Irish money. He realises that Nolan was part of a major Dublin bank robbery some years previously and has thus hidden the money. With Ray's help, Arthur manages to inform DS Morley of what's been happening and an operation is set up to arrest Nolan and his cronies.
