Ferdinand Mount 
Jem (and Sam) 

How does Jeremiah Mount, the dealer in pornography, come to be the lover of the Duchess of Albemarle and the colleague of the great Samuel Pepys? In Pepys‘ Diary, Jem Mount plays a shadowy role, but in Jem’s own memories Sam looms large. Friends and drinking partners at first, they become vicious rivals for fame and women. In his struggle to survive and triumph over his adversary in a rackety world, Jemm stumbles into many trades: chemist, butler, soldier, secretary and, now and then, lover.This ’newly discovered autobiography‘ – with its disconcerting echoes of our own time – takes its dubious hero from the shaky days of Cromwellian England, through the unbuttoned license of the Restoration, to the panic of Monmouth’s Rebellion and the Jamaica sugar boom.
