Another of my recent acquisitions: the 3rd edition (1936) of Strachey's book, published by Victor Gollanz Ltd.
I only knew of the book and its author from articles in the Socialist Standard, like the one in the picture.
Strachey had a rather muddled political career. He joined the Labour Party in the 1920's. He left with Oswald Mosley, only to leave the New Party and join the CPGB when Mosley began drifting to overtly fascist politics, He then left the Communist Party, after the Molotov-Ribbentrop Pact, for another spell in the Labour Party, where he held a few ministerial posts and served as MP for Dundee from 1943 til his death. He was a widely read author in the 1930's and helped Gollanz found the Left Book Club in 1936. (Details from Wiki, retrieved 24/10/15.)
As for the SPGB's views on the issue, there is a plethora of material in my archive or at the SPGB website and/or in David Perrin's book on the Socialist Party.
