Mystery, Ink: Murder Times Two

Nattie Ryan's bookstore, Mystery, Ink, is dying right before her
eyes, and her beloved son, Jeffrey, is in prison for drug trafficking,
a crime he didn't commit. Yet nothing compares to the complications
in her life when she discovers her friend, Clyde Hamilton,
sitting on a park bench, strangled in the same manner as the
unsolved murder, 30 years before, of Doctor Adams. The police
arrest a drifter who is passing through Centerville, but Natalie
knows they have the wrong man, because he has no knowledge of
the first murder. To avenge the death of her friend, she sets off on
a harrowing journey that plunges her into danger with deadly
consequences.
