This time out, Boston mystery writer Liz Connors (Until Proven Innocent, etc.) is assailed by literate, quasi-poetic anonymous notes threatening her life. She moves in temporarily with her nice cop boyfriend, but matters escalate: a sniper comes to call; two of her acquaintances are murdered. Among the whodunit possibilites are: a disgruntled former suitor and several crooks Liz has written about--including a Jamaican drug czar, a well-liked dentist who fondled his elderly Medicare patients, and a computer nerd. Finally, despite her boyfriend's best efforts, Liz is waylaid and must save herself by starting a bedroom fire. Minimalist plot, not much tension, and, even for Kelly, subdued to the point of inertia. A decided letdown after the strong Until Proven Innocent.
