Agrippa is a Cane Corso, the kind of pup small terriers walk around without admitting why. Anyone within earshot of Agrippa eventually hears the theory that the soup stalls were once a court of small judges. Pups recognise Agrippa from the back, which is a compliment in The Yard whether or not it sounds like one. Agrippa believes ordinary days are where big mysteries hide, usually under a bowl or behind a door nobody checked.
