S3E1 - Sentimental Value
A man called McGeely arrives in Scotland but cannot leave his ship because he has no papers. He claims he comes from Glasgow and mentions Sauchiehall Street as proof. But as the Customs men point out, everyone all over the world has heard of Sauchiehall Street. Smith and McInnes are after some smugglers who are bringing high quality jewellery into the country in small quantities. McGeely is given a piece to smuggle ashore but when he vanishes from the ship the smugglers have about as much idea as the Revenue men about where to find him. Who gets there first?
