Bauer Books & H. G. Wells 
The Man Who Could Work Miracles 

The story is an early example of Contemporary fantasy (not yet recognized, at the time, as a specific sub-genre). In common with later works falling within this definition, the story places a major fantasy premise (a wizard with enormous, virtually unlimited magic power) not in an exotic semi-Medieval setting but in the drab routine daily life of suburban London, very familiar to Wells himself.
