Vittorio Vidali: Italian revolutionary and Moscow’s eyes in Mexico, with an alias for every day of the week. Same “side” as Mella but with a different agenda. Vidali is involved in Mella’s assassination (as well as an assassination attempt on Leon Trotsky), and ultimately convinces Tina to follow him to Moscow where she is recruited as an operative. Loves danger. Loves Tina . . . Enough to kill her when she tries to leave him?
