TFW, while researching one fiction project, you stumble upon a Wikipedia paragraph which could serve as the seed for another project entirely:

A.A. Milne, the author of Winnie the Pooh, served in MI7(b) after recovering from wounds sustained at the Battle of the Somme. The Anglo-Irish fantasy writer Lord Dunsany served with Milne after being wounded in the Easter Rising; his books Tales of War and Unhappy Far-off Things collect some of the material he wrote during this time.

One wonders what sort of things those two discussed over their plausibly liquid lunches along the Strand?
