American tourists in London have been falling for the lost wallet scam.
A retired major approaches a tourist claiming to have found their wallet. Thye then trace the actual owner who thanks them and tells them it contained important information of a big share deal. An easy way to double their money.
They are invited to buy the shares, but it has to be immediately. The tourist later finds out that they have run off with the money and they are no shares.
DI Maguire pretends to be an American tourist but his accent gives him away to the associates of the major.
A decent if flawed episode. I had no idea why the two con men want to bump off the unfortunate American tourist.
They were still in Maguire's radar.
