The Delavine Affair is a snappy B movie from 1954 (some sources say 1955) which was based on a story called Winter Wears a Shroud, written by Robert Chapman. I've not been able to find out anything much about Chapman or the original story, but the film is a competent mystery which, like so many crime films of that era, featured some very good actors as well as the occasional rather wooden lead.
The lead in this case is Peter Reynolds, who hailed from Wilmslow, and sadly died young. Here he plays a newspaper agency man called Banner who is contacted by a hellfire preacher called Gospel Joe. But when he goes to see Joe, he finds him dead. The police turn up, having been tipped off that Joe has been mrudered, and our hero becomes the prime suspect.
He has the good fortune to be married to Honor Blackman, but she thinks he spends too much time at work, and has taken up with an admirer played by Gordon Jackson. Banner discovers that there appears to be a connection between Joe's death and a robbery - the as yet unsolved Delavine jewel theft - which took place some time back.
Banner's investigations bring him into contact with a mixed bag of characters, played by Michael Balfour and Katie (The Ladykillers) Johnson. There are a number of pleasing plot twists, and overall this is a decent crime film, unpretentious but perfectly competent. I'd be interested to know more about Winter Wears a Shroud, if any readers of this blog are familiar with it.
