Violets are blue - James Patterson

The mastermind of ROSES ARE RED is back - and he's hot on Alex Cross's trail. Meanwhile, Alex is drawn in to his most bizarre investigation yet. Two San Francisco joggers are found dead - bitten and hung by their feet to drain the blood from their bodies. Further murders in California, and then on the East Coast as well, completely baffle Alex and the FBI. Is this the work of a cult, of role players, or even of modern-day vampires? Desperate to stop the deaths, Alex teams up with Jamilla Hughes, a savvy woman detective from San Francisco, and the FBI's Kyle Craig. The result is two fantastic mysteries in one non-stop thriller that will have readers furiously turning the pages all over the world.
