Blanche Fury, a 1948 historical melodrama starring Stewart Granger and Valerie Hobson, was based on a book of the same name by Joseph Shearing published nine years earlier. The Shearing pseudonym was used by Marjorie Bowen, a highly prolific and undoubtedly accomplished writer, and the Shearing stories were typically based on real life historical cases. For instance, Airing in a Closed Carriage is based on the Maybrick case.
Blanche Fury was inspired by a real life case rather less well-known than the Maybrick case, although quite notorious in its day. This was the double murder at Stanfield Hall in Norwich in 1848, when a father and son were shot dead by a tenant farmer. The details of the case are significantly changed in the film, not least in the transposition of the setting to Staffordshire, but perhaps the most significant change is the focus on the title character, played by Hobson.
Blanche is a strong woman, well-born but poor, who yearns for position and affluence. She is doing drudge work as a companion when she's contacted by Simon Fury, who wants her to come to Clare Hall, and look after his grand-daughter, Lavinia. Lavinia's father is played by Michael Gough, and he takes a shine to Blanche. But so, unfortunately, does the much more charismatic Philip Thorn (Granger) who believes he is the rightful owner of Clare, and has been denied his inheritance by the unfairness of the laws on illegitimacy.
There's a doom-laden feeling to the story, which proceeds at a sombre pace. By modern standards, the presentation of a gang of villainous gypsies seems like a classic example of unpleasant stereotyping, but leaving that issue aside, the story is quite a good one. It is, as I say, more of a melodrama than a murder mystery, but it's quite watchable The script was co-written by Audrey Erskine Lindop, who would later write I Start Counting, a novel which also became a successful film..
