Book excerpt: "Cigars all around"( LOUISE URE, SHAMUS AWARD-WINNING AUTHOR) for the new Maternal Instincts mystery series. First-time mom Kate Connelly is bringing up baby- and bringing down a killer. Kate Connelly may have found the perfect work-from-home Mommy job: private investigator. After all, the hours are flexible, she can bring the baby along on stake-outs, and if you're going to be up all night anyway, you might as well solve some crimes. But when a body is pulled from San Francisco Bay that may be her brother-in-law, Kate must crack the case faster than you can say "diaper rash" in order to keep her family together.
