A routine visit to his doctor has unforeseen consequences for George Bradstock. During his consultation, he discovers that the doctor's car is for sale and buys the vehicle. The doctor has however, unwittingly left something in the back that leads George to encounter the mysterious Doctor Mulecannary.
George Bradstock is happy in his somewhat humble occupation. He is a bank teller at a branch of Martins Bank in London. George does not earn very much and this prompts his ambitious wife, Dorothy to urge him to seek promotion.
Eager to please his wife, and having no luck stepping up through the ranks to become manager of the bank, George becomes involved in Doctor Mulecannary's money making scheme that does not go completely to plan.
While George maintains his faith in the ultimate good intentions of the doctor, Dorothy loathes and mistrusts him; she tells her husband to have no more dealings with Mulecannary.
Just who is Doctor Mulecannary? The man is at first a mystery as he leaves no clues to his identity. Eventually, step by step, George discovers who he really is, but only after some strange and life changing events take place.
The reader can decide whether Doctor Mulecannary is a man of business, a crook and confidence trickster, or a medical genius.
