Pit of Darkness

William Franklyn, whose voiceover of Schweppes adverts would become a TV feature, posts a highly convincing performance here, hardly ever leaving the screen, and somehow reminding me of a younger Rex Harrison. He certainly looks suitably bamboozled to begin with, as he carefully pieces together his three weeks' absence from work and home.

Director Lance Comfort, about whom I am embarrassed to admit I know nothing, intelligently puts together a maze of flashbacks and throws in quite a few suspects until Logan (Franklyn) works out the enigma - and that begins with firm partner "enigmatically" telling him about the Ethiope's Ear, subsequently identified as the 250,000 quid diamond stolen from a tycoon called Tuscan.

Why that partner knows that crucial detail, and even recites it to him in his wife's presence - lovely Moira Redmond - is never explained and has to go down as a big minus, costing my rating one star. It deliberately deceives the viewer and detracts from the plot's credibility.

Otherwise, logical incidents advance a riveting and fluid story line, cinematography by Emmot and editing by Trumper are first class, and even the recurrent song, My Heart Is the Lover, by Martin Slavin, is really catchy.

Leonard Sachs plays the foreign-accented villain unctuously enough.

Not perfect, no masterpiece, but no waste of 79'. Recommended viewing if you like film noir.
