I'm currently reading Murder in Little Shendon by A.H. Richardson. This book is the first in the Hazlitt/Brandon Series of murder mystery novels.
No one in Little Shendon much liked antique store proprietor Mr. Fynche, but his gruesomely violent death was shocking. Was this a robbery gone bad, something to do with Fynche's prior work with MI5, or something else altogether? At the request of Scotland Yard Sir Victor Hazlitt and the actor, Beresford Brandon, decide to come to the quiet village to see what they can uncover.
