August's Heat (Larry Macklin Mysteries Book 10)

Criminal investigator Larry Macklin faces a classic who-done-it when
Conrad Higgins, a local antiques dealer with questionable ethics, is
found shot in his own home.
Larry soon realizes that half the
town had reason to hate the man. Is the murderer the next door neighbor
with an ax to grind? The friendly nursing home volunteer who believes
Higgins swindled her mother? The rich silent partner with a checkered
past? Or even Higgins’s nephew, who’s on the run from his own personal
demons.
Larry barely has time to wrap his brain around all the
options when one of the suspects is viciously attacked and another
disappears. It’s going to take all his skills as an investigator, and a
little help from his partners and friends, for Larry to crack this case.
