The Stranger in Room Six

It's been fifteen years since Belinda was convicted of her husband's murder. Now that she's free, she's ready for a fresh start. So, when she
gets a job at Sunnyside Home for the Young at Heart, she's dead set
on making sure no one learns about her awful past.

Mabel has spent her life at Sunnyside--first as an evacuee during the
Blitz, and now as the home's oldest resident. She's held the secrets of
this house for as long as she can remember. Secrets that, in the wrong
hands, could kill.

But history won't stay hidden forever, because someone is onto both
Belinda and Mabel, watching and listening from Room Six.

And they'll stop at nothing to find out the truth.
