A Storm of Swords
Dirk is part of the great ranging, the force that leaves Castle Black in search of wildlings. Dirk is one of the conspirators who intend to kill Lord Commander Jeor Mormont and others. His part in the conspiracy is to kill Blane.
Dirk is among the survivors of the fight at the Fist who retreat to Craster's Keep. Dirk blames Craster when Bannen dies. After members of the Watch insult their host to the point of his attacking them, Dirk slits Craster's throat, killing him during the mutiny at Craster's Keep.
A Feast for Crows
Dirk remains at Craster's Keep after the betrayal, along with a few other former members of the Night's Watch.
