And when she was good - Laura Lippman

In the comfortable suburb where she lives, Heloise is just a mom,
the youngish widow with a forgettable job who somehow never misses her
son's soccer games or school plays.

But in discrete hotel rooms throughout the area, she's the woman of your dreams - if you can afford her hourly fee.
For
more than a decade, Heloise has believed her unorthodox life to be a
safe one; rigidly compartmentalized, maintaining no real friendships and
trusting very few people. But now this secret life is
under siege. Her once oblivious accountant is asking loaded
questions about her business. Her longtime protector is hinting at new,
mysterious dangers. Her employees can no longer be trusted. Her ex, the
one who doesn't know he's the father of her son, is appealing his life
sentence. And, one county over, another so-called 'suburban madam' has
been found dead in her car, an apparent suicide...

Can Heloise stay alive long enough to remake her life
again, and save her son? Can she really expect to leave everything else
behind?
