Pit of Darkness (1961)

This is quite an engaging story of a man "Logan" (William Franklyn) who comes to on a bombed-out Wapping waste ground with a bloody head. On returning home, he discovers from wife "Julie" (Moira Redmond) that he has been AWOL for three weeks - and he has no idea what happened in the intervening time. It soon becomes clear that his mysterious disappearance is connected with his business - he designs and instals safes - and he must try and piece to gather what happened. Neither the writing (it's a bit repetitive) nor Franklyn are great, to be honest, but Nigel Green and Leonard Sachs (with Tony Booth) help chivvy things along now and again. It's pretty obvious why "Logan" was the target, but the perpetrators remain a mystery til quite near the end and as low budget Butcher's efforts go, this is up in their upper echelons with a smidgen of psychology injected into the plot, too. Could have done without Ronnie Hall and his crooning, though....!
