A not-so-anonymous victim sends Reuben Frost on a chase to catch a high-tech killer

The girl is found lying beside the East River, strangled. She's in her late twenties--so why was she carrying a fake ID? The case should have nothing to do with Reuben Frost, legendary retired Wall Street lawyer, but Frost has never been known to mind his own business. Not to mention, his wife, Cynthia, has been slowed down by arthritis, and his social calendar is barren for the first time in decades. It's the perfect time to find a murderer.

The dead girl is Marina Courtland, daughter of millionaire food distributor Daniel Courtland, a treasured client of Frost's old firm. Working alongside his dear friend Luis Bautista, the sharpest detective in the NYPD, Frost digs into Marina's past. But what he discovers is a tangled web of plagiarism, infidelity, and indiscreet emails that will ultimately put him face to face with Marina's killer.

Murder.com is the 8th book in the Reuben Frost Mysteries, but you may enjoy reading the series in any order.
