Unmasked - BOONE-BELL, #4

It was nearly midnight on a Saturday night in early June. Boone received a call from Mazie Tucker, the wife of New York State Police Detective George Tucker, a close personal friend of Boone's. Mazie had returned home from a night out with friends to find Tuck in his recliner, dead, apparently from a self-inflicted gunshot wound. The flat-panel set was blaring a cop show, the volume turned up as high as possible.
Unable to accept her husband of thirty years would take his own life, and distressed by State Police focusing on suicide, Mazie reached out to the only person she could trust. Marianne Bell, Boone's partner, tries to help a young woman victimized through identity theft. Even though she eventually solves the case, her client's subsequent actions, undertaken despite Marianne's advice, result in tragedy.
As Boone investigates the circumstances of Tuck's death, he is faced with two possible suspects, neither of which he feels responsible, even when one of them is charged with the murder as a result of DNA evidence. Only through dogged pursuit of available leads does he learn the identity of the killer. But will he be in time to prevent another killing?'Unmasked' reintroduces the character of Alexandra Burton from the earlier work, 'Lens Capture, ' where readers also met Tuck for the first time.
Alex is now a New York State Trooper and possible ally of Boone's. Or is she something different?
