This episode is a blatant copy of the far superior "The Stranger Left No Card" (1952) q.v. But since that award winning British short seems to be no longer available I suppose we can't fault the producers of the series 'Tales . .' for enabling its audience to experience this gem of a story of the perfect(?) crime. But once you've seen a classic original nothing comes close and although Derek Jacobi does his best he is woefully let down by a usually reliable Clive Swift in his pre 'Keeping Up Appearances' days who plays the villain more like a friendly old grandfather. And with modern police methods no way would this prank be successful today. Maybe not even then.
