Focus on Crime — John Buxton Hilton

When a pastor is caught breaking the Eighth Commandment, he asks that Kenworthy be put in charge. But it's only when the clergyman's corpse is found--and the shop-lifting case becomes a murder case--that the inspector steps in... discovering a chain of deception and evildoing that goes all the way back to wartime. The war may be long over, but Kenworthy will have no peace until he finds the truth...

AN INSPECTOR KENWORTHY MYSTERY
With a pipe in his hand and a trick or two up his sleeve, Inspector Kenworthy is Scotland Yard's consummate master of investigation. Big, bearish, and sometimes bullying, he makes his sergeants quake and culprits tremble--for Kenworthy's keen eye for spotting "whodunnit" lets no one get away with murder.
