Does anyone know Hugh Walpole?

I read one of his books almost a year ago, it's called The Other Man (I'm not sure if that's the English title), And when I searched for content, I only found one or two short videos about the book. 

I loved his work; it's short, about 260 pages if I remember correctly. I felt uneasy when I read it.

Please, if somebody knows him, recommend more of his works to me.
