The Deadly Truth by Helen McCloy
My rating: 4 of 5 stars

Dr Roger Slater has developed a new 'truth drug' which he believes friend and socialite Claudia Bethune has stolen a sample because she believes that it would be fun to use on her house guests at Blessingbourne. Dr Basil Willing is her tenant for the season, and investigates the aftermath of the dinner party with the aid of the local police.
An entertaining and well-written historical mystery with its cast of varied characters. A good addition to the series which can easily be read as a standalone story.
An ARC was provided by the publisher via Netgalley in exchange for an honest review.

Originally written in 1941
