Wallace, Edgar: Captains of Souls (1922), v1
 

Ambrose Sault has lived a rough life. He himself admits to being in a Caledonia jail for murder when he was rescued years ago by his partner, Moropulos. But inside him resides the gentle soul of a poet and philosopher. This is what draws to him the disparate lives of Christina Colebrook, cynical invalid of his landlady, and Beryl Merville, the esteemed doctor's daughter, now under the sway of the ruthless Jan Steppe.

An unusual and ambitious venture on Wallace's part, 90,000 words long, and with overtones of the supernatural.
