One of the Prion Lost Classics reissues was Burgo Partridge's A History of Orgies. This caught my eye for more than the obvious reason. Burgo was the son of Bloomsbury Group leading lights Frances and Ralph Partridge. See Frances obits from The Times and the Independent.The obits give good background on the Bloomsbury troop of nonconformist artists, writers, and hangers-on.
Frances wrote A Pacifist's War: Diaries 1939-1945: Volume 1, which I reviewed here.
