He was foiled in his murderous attempt by Stanley Howler who, when confronted by Gryle, had one of his "Little Moments", and hit Gryle in the mouth with a sack of pins. However, he was only given a vague description and assumed the man wearing the Postmaster's hat must be Moist when in fact it was Acting Postmaster Tolliver Groat instead. He was then hired to destroy the Ankh-Morpork Post Office and assassinate the Postmaster Moist von Lipwig. He murdered Reacher Gilt's fellow Board member Crispin Horsefry when Crispin begins to panic and get cold feet about the Grand Trunk's business practices. He was responsible for the death of John Dearheart at the beginning of the novel who Reacher Gilt wanted disposed of because he was starting a rival Clacks system. Gryle was the ideal assassin because he could arrive by air and leave few clues for anyone in the Watch to decipher, as well as having little tangible smell for a werewolf like Angua to identify. Gryle was a feral one as he was a ruthless killer who worked for Reacher Gilt, the evil Chairman of the Board of the Grand Trunk Clacks network. In earlier novels, the reader had been told that Mr.Ixolite, who is a member of Reg Shoe's Fresh Start Club was the Disc's last surviving banshee but perhaps Pratchett was referring to "civilized banshees' rather than feral ones. He had very few needs in life, but he did have a passion for pigeons, not the best passion in Ankh-Morpork where the pigeons are particularly toxic, "dogturd burgers". An extremely unlikeable character, he told Stanley Howler that he "gnawed his grandmother's bones". The muscles in his chest were immensely tough, protecting as they do both his hearts. He appeared to be wearing a thick leathery cape, but that was really his wings tightly wrapped around him. Mr Gryle was a banshee who made his appearance in the novel, Going Postal.
