Look what I found today at Book Warehouse! I'm so pumped! Lovely Dover editions of nearly impossible to find (according to Dover) mysteries by R.T. Campbell. Campbell is the pen name of Scottish author Ruthven (pronounced riven) Campbell Todd. Born in Edinburgh in 1914 he was a poet, art critic, scholar and novelist of children's books and science fiction. He wrote eight mysteries in 1945 and 1946 but abandoned detective writing for other literary projects. $2.99 each! Fantastic find! Can't wait to finish The Chessmen to dig into one of these!
