A Game of Thrones
A Clash of Kings
Lord Gyles attends the tourney on King Joffrey's name day. When he receives his copy of Stannis Baratheon's letter concerning the illegitimacy of Queen Regent Cersei Lannister's children with King Robert I Baratheon, Gyles sends it on to King's Landing. Due to the War of the Five Kings, King's Landing is supplied mainly by Gyles and Lady Tanda Stokeworth, for their lands are far enough away from the fighting to be untouched by the war. Gyles is present when Tyrion Lannister offers his terms for peace for Ser Cleos Frey to take back to Robb Stark, King in the North.
Lord Gyles survives the attack by the mob on the procession returning to the castle after seeing Princess Myrcella Baratheon off to Dorne. After the attack, Cersei fears for her son's life and decides to send Prince Tommen Baratheon in secret to Rosby, dressing him as a page and putting him under the protection of Gyles. Tyrion finds out about the plan, however, and has Gyles and his entourage intercepted on the Rosby road by Ser Jacelyn Bywater. Tyrion decides to release Gyles.
A Storm of Swords
Gyles is an attendant at the wedding of Sansa Stark and Tyrion Lannister. Lord Rosby accompanies Tyrion when he is sent to meet the delegation from Dorne. Tyron displaces Gyles of his spacious apartments at the Kitchen Keep in the Red Keep.
During the wedding feast of King Joffrey I Baratheon and Margaery Tyrell, a melon lands in Lord Rosby's lap when dwarfs reenact the war. Gyles is called as a witness for the prosecution in the trial of Tyrion for the death of King Joffrey I Baratheon. He tells of how he saw Tyrion fill the wedding chalice.
A Feast for Crows
After the funeral of Lord Tywin Lannister, Gyles tells Queen Regent Cersei he has commissioned a statue of Lord Tywin to be placed by the Lion Gate in King's Landing. Rosby's coughing has gotten much worse and he is beginning to cough up blood. Cersei learns that Tywin had named Garth Tyrell to become the new master of coin and, in order to prevent another Tyrell from joining the council, she lies to Lord Mace Tyrell, telling him she has already named Lord Gyles as the new master of coin to the small council instead.
Upon assuming the duties of the master of coin, Gyles has to deal with many of the crown's debt problems and Noho Dimittis, an angry envoy from the Iron Bank of Braavos, who is irate when he learns that the king would suspend all payments on the loans from the Iron Bank until the War of the Five Kings is over. The envoy hounds Gyles so much that he takes to his bed coughing up blood.
Despite Grand Maester Pycelle's treatments, Gyles is overcome by his sickness and dies at the Red Keep. Cersei's paranoia leads her to the mistaken belief that Gyles was killed by the Tyrells so that they could replace him with Garth Tyrell. Cersei threatens Pycelle by insinuating that he killed Lord Rosby. Gyles does not leave behind an immediate heir, but he does have a ward at Rosby. 
Lord Gyles has been threatening to die for as long as I have known him, but he is still with us, and will be for many years, I do hope. No doubt he will cough the whole lot of us into our graves.
