Comes the Blind Fury by Douglas Rutherford was first published in 1950.
Harry Forsythe and Paddy Regan had been in the army together in WW2 and they have been having a bit of a hard time settling into civilian life at the end of it all, they decided to set up a detective agency. They were just beginning to think that it was a mistake as they had no clients at all, when one turned up in the shape of Angela Dove, a young woman who was worried about her brother Robert. He had gone to France and Angela hadn’t been able to contact him at all. She’s worried as their step-father is a wealthy businessman, and she suspects that someone might have kidnapped Robert.
Harry gets the job of going to Paris to try to track Robert down, but his subsequent phone call to Paddy ends abruptly and Paddy fears the worst. Of course Paddy has to follow his partner to Paris to see what has happened.
I don’t want to say much more about the plot, but it features Scotland Yard and a chase to Zurich. I really enjoyed this thriller, I think it’s the first book that I’ve read by Douglas Rutherford whose bio on the back of this Penguin crime reads like one of those spoof bios you sometimes see. He was a Counter-Intelligence Officer in WW2 and that background in espionage and international crime obviously gave him the ideas for his writing career.
I must say though that whenever I read about a private detective and a young female client I inevitably think of Bogart and Bacall, but this book doesn’t seem to have been made into a film.
