I picked this book up for 10p today at a local Street Fayre.
It is described as "A drama of contemporary behaviours" and starts in the RA Mess at Woolwich.
Evidently Frankau was an infantryman in the 9th Batt East Surrey Rgt eventually becoming a Captain in 107th Bde RFA 24th Division before being invalided out in February 1918.
He wrote for the "Wipers Times" and published many poems and other books including "Peter Jackson, Cigar Merchant" which is discussed elsewhere.
Now I must find the time to read it!
