He Huffed and He Puffed [EPUB ebook] 

To find a blackmailer’s killer, Marian Larch investigates the extortionist’s victims A. J. Strode would kill for command of House of Glass, the corporation that controls everything from plate-glass windows to fiberglass insulation, and he nearly has it within his grasp. Only three stockholders—a violinist, a helicopter pilot, and a mercenary—stand between the businessman and his goal. But no matter how much Strode offers, they refuse to sell. And when money doesn’t talk, he turns to blackmail. Strode invites his three targets to his townhouse, intending to close the deal once and for all, but his plan backfires. When Strode is found in his library with three knives buried in his chest, the case falls to Marian Larch, a no-nonsense NYPD detective who’s hardly prepared for the brutality she’ll find inside House of Glass.He Huffed and He Puffed is the 2nd book in the Marian Larch Mysteries, but you may enjoy reading the series in any order.
