  This has some good ideas and research, but the author seems fixed on the idea that the message was produced by an SOE agent using a poem cypher. This seems unlikely to me because the cyphertext is written on an official-looking form. Blank message pads and quantities of homing pigeons are presumably not something that an under-cover agent would want to carry around with them.
