Sinclair’s densely woven stalking of London’s hidden currents and some of its more uncherished denizens led to a cult author becoming national best-seller. Ballard was both friend and mentor. Burroughs touched Sinclair by sending him a piece for a student magazine – they continued to correspond. Gibson – met at a talk – proclaimed him his favourite writer. Snyder was visited on an American road-trip. Petit was one of many collaborators and comrades-in-arms – they made a film about Whitehead (in which Acker appeared), rubbing him up the wrong way. Sinclair only once encountered W. G. Sebald; they did not speak.
