Letter from David Lockhart Robertson Lorimer to Sidney John Duly in which he apologises for his behaviour concerning oranges but all his time has been taken up with sorting the ARP and "Black-out".

He feels the problem is spiritual and that he does not feel at home in a world of Hitlers and Chamberlains. Lorimer is returning Duly's "Latent Defect" and adds his comments on it. Written from Welwyn Garden City, Hertfordshire. Handwritten with embossed letterhead, 2 pieces, 3 sides, dated 11 November 1938.
