Discworld Characters - Doughnut Jimmy

Universally known as Doughnut Jimmy, Dr James Folsom is a highly proficient horse doctor who was brought in, under threat of blackmail from Samuel Vimes, to treat Vetinari in Feet of Clay; this rather odd choice being the result of Vimes' knowledge that any human doctor would be contracted to guilds (who all resent Vetinari to varying degrees) and that horse doctors, treating animals worth considerable amounts of money, faced considerable amounts of trouble should their patients die. Due to his lack of experience with human patients, much of his advice was flawed ("walk him round a bit on loose rein...and no oats"). A former jockey, he won a lot of money by not winning races. Highly skilled at achieving results, when he treated the racehorse Dire Fortune, it didn't fall over until the last furlong. A considerable testament to his skills, considering that the horse had, in fact, died coming up to the starting line.
