Rick, an older, married man is besotted with Fiona, his mistress, and she with him.
Rick's wife Lydia is determined to keep her home, even if Rick is not there to enjoy it with her.

A slow burn thriller, but gripping. Twists that I didn't see coming, and characters that are unlikeable.
The wife is a strong character, but the mistress is as well, but the mistress is needy and somewhat desperate.
Put them together, with a few lies, and there are tragic events.

Valerie Keogh has done it again - a great unputdownable thriller.

I was lucky enough to read an early copy of His Other Woman. I read it in one sitting! Keogh continues to go from strength to strength with her thrillers. All different but also all excellent, compelling stories.
Fiona might think she has it all. Rick has other ideas, as does his wife! The eternal triangle but here nothing is as it seems. The ending was a huge surprise.
