The Second Key - Elena Hartwell

She thought she knew her husband. She was wrong.

When Marcus Ashford dies in a late-night car crash, Claire is left to grieve the man she thought she knew completely. Eight years of marriage. A beautiful flat in Notting Hill. A life that made sense.

Then she finds the key.

It belongs to a flat in Bermondsey - rented under a name she has never heard. Inside: a second phone. A laptop. Cash. And evidence of a life Marcus had been living in parallel for years.

As Claire follows the trail her husband left behind, she discovers that the man she loved was not who he claimed to be - and that the people he was working for will do whatever it takes to keep his secrets buried.

She is grieving. She is being watched. And she is getting closer to the truth.

The Second Key is a gripping domestic thriller for readers of Lisa Jewell, Lucy Foley, and Liane Moriarty - a story about the lives we build on lies, and the women who survive them.
