The Assassins' Guild follows strict professional guidelines, with members behaving at all times in a gentlemanly manner. The guild is one of the richest in the city, and runs its own school, like the thieves. Unlike the thieves, however, the school is one of the most exclusive, and sons of the nobility - and now daughters - attend, though some are "excused stabbing". The school also educates scholarship boys - frequently from the Shades, and other poor areas of the city, these are the kind of people who are good at killing, Mr Teatime and Inigo Skinner being notable scholarship students in the guild school. To date, there are two people in Ankh-Morpork known to have had contracts refused on, and no longer be available for assassination - Lord Vetinari and Commander of the Watch, Samuel Vimes. These two people are both too difficult to assassinate, and too important to the stability of the city, to be assassinated, though for a long time the guild was employed to - and failed - to assassinate them both by various members of the nobility.
