My second nomination is The Forgers by Bradford Morrow.

From Goodreads:

The rare book world is stunned when a reclusive collector, Adam Diehl, is found on the floor of his Montauk home: hands severed, surrounded by valuable inscribed books and original manuscripts that have been vandalized beyond repair. Adam's sister, Meghan, and her lover, Will--a convicted if unrepentant literary forger--struggle to come to terms with the seemingly incomprehensible murder. But when Will begins receiving threatening handwritten letters, seemingly penned by long-dead authors, but really from someone who knows secrets about Adam's death and Will's past, he understands his own life is also on the line--and attempts to forge a new beginning for himself and Meg.
