Georgette Heyer's Duplicate Death is an excellent fast placed mystery story featuring Chief Inspector Hemingway who features in other books as a Sergeant. A Bridge party leads to strangulation via picture wire of a very unpleasant character - Dan Seaton-Carew. There are many clues and a similar number of red herrings and it is not until a second murder takes place that Hemingway is able to work out what happened.
Major Pettigrew's Last Stand by Helen Simonson is one of those quirky village England stories which I really like. The Major is still trying to come to terms with the death of his wife Nancy when his only brother, Bertie, dies. This strangely enough is the catalyst for him getting to know Mrs Ali - a widow who runs the village shop with her nephew. I've read about a third of it so far and I really like it. The characters are believable and eccentric and the plot intriguing. But this is a novel of character and every day events rather than anything very dramatic.
