After refusing to accede to his ex-mistress's request that he tell his pregnant wife about her Gabriel gets a visit from Beatty, who turns out to be a customs officer. He tells Gabriel that Harvey Wratten got his pardon for saving his life and also giving a tip-off about a drug deal, though the drugs turned out to be already in Harvey's possession, hence the rift with Babur, to whom he did not deliver. Beatty also arrests one of Harris' pushers, Harris's rent boy lover naming Jay Wratten as the informant, though Wratten denies this. Through studying CCTV, Gabriel links Dixon to Gatehouse, who is now in pursuit of Peter Glickman, an elusive associate of the Wrattens.
