The Dark River
First published in London by W. Collins Sons, 1919
It is nearly impossible to find a copy of the Collins first edition, and I do not own a copy
First published in New York by Thomas Seltzer, 1920
I own two variant bindings, and believe the one with gold titling to be the preferred first edition. The second binding also has an original dust jacket, which is extremely rare.
I own a Collins reprint, circa 1920s/1930s
I own a couple of Constable Miscellany reprints
The facsimile dust jacket shown below was made from my copy's original dust jacket
