A racehorse that unaccountably failed to win the Quirm $100 steeplechase. This resulted in Chrysoprase, the troll businessman and upstanding pillar of his community, losing $10,000.

Samuel Vimes proposed that this happy state of affairs could continue just so long as Jimmy assisted the Watch with their enquiries. Jimmy temporarily joins the Watch in Feet of Clay.
