Gray (Down These Mean Streets A Man Must Go)
From Tardis Wiki, the free Doctor Who reference
Mr Gray was an individual who came looking for Gustave Lytton in 1975.
He met with Lytton outside the Jazz Soiree Club, alongside his associates, Mr Stein, Mr Smart and Mr Standing. He was punched by Lytton after vaguely threatening him, and left face-down in a pile of his own blood. (COMIC: Down These Mean Streets A Man Must Go)
