Operation Safecrack

John Mills is a retired safe cracker who has paid his debt to society and doesn't want to crack another safe.

David Healy works for a firm manufacturing safes who has the bright idea of hiring the world's most famous safecracker showing their newest safe can't be cracked.

Mills' attempts at cracking the safe are redundant. Even at half an hour it feels long. But Mills is able to overcome even this.

One disappointment: David Healy is a bit overwrought at the twist ending. Had he underplayed his part the episode would have been improved.

Nevertheless, it's a tricky episode with excellent acting from Mills, though Healy, an actor I like, occasionally overplays his hand.
