The Bells of Old Bailey — Dorothy Bowers

It was not until the fifth death in Long Greeting that Miss Tidy made up her mind to go to the police. And then from no sense of civic duty but because she knew her own security imperilled. So opens the fifth and final book by Bowers, first published in 1947, one year before her untimely death from TB at the age of 46. Scotland Yard is once again involved but Dan Pardoe, the investigating officer in the four previous books, has been replaced by Detective Inspector Raikes.
