Nicholl, Charles (1993). The Reckoning: The Murder of Christopher Marlowe. University of Chicago Press. pp. 327–328. ISBN0-226-58024-5. "According to the official story – the story told by Skeres and Poley – it was Marlowe who pulled the knife and Frizer who killed him in self defence...I believe that in this, as in so much else in their careers, Skeres and Poley were lying...Ingram Frizer may well have struck the fatal blow. It is probable, though not certain, that he did."
