Harry Potter and the Prisoner of Azkaban Twelve years into his sentence, Sirius sees a picture of the
Weasley family on the front cover of the
Daily Prophet. He notices the pet rat Scabbers perched on
Ron Weasley's shoulder. This serves as a turning point in the series and sets the events of the third novel in motion, as Sirius immediately recognises Scabbers as Pettigrew's Animagus form. He realises that stationed at Hogwarts, Pettigrew will easily be able to deliver Harry to Voldemort should Voldemort ever regain power. This knowledge clears his mind and gives him the mental strength to escape Azkaban. He is the first person known to have escaped the wizard prison by his own means, accomplishing this feat by transforming into his Animagus dog form. The
dementors' inability to detect Animagi, along with his severe weight loss from malnutrition, allow him to slip through his cell bars. After his escape, Sirius takes refuge in and around
Hogsmeade, intent on exacting revenge upon Pettigrew and remaining near Harry. Knowing that the dementors have been stationed around Hogsmeade and at Hogwarts, Sirius remains in his Animagus form during this time, and is able to enter the Hogwarts grounds without being recognised by the dementors. Harry catches several glimpses of Sirius in his dog form and mistakenly believes him to be the
Grim. He befriends
Hermione Granger's cat
Crookshanks, who is aware that Sirius is not actually a dog and who recognises Pettigrew for what he really is. Sirius breaks into Gryffindor tower at one point with a knife looking for Pettigrew, having had Crookshanks obtain
Neville Longbottom's list of the dorm passwords, and shreds Ron's curtains after finding Pettigrew gone, due to Pettigrew having faked his death and framed Crookshanks. After Harry's broom is destroyed by the Whomping Willow during a Quidditch match invaded by Dementors, Sirius anonymously sends Harry a Firebolt as a Christmas gift, although it is confiscated by
Professor McGonagall on suspicion that the broom is jinxed. Towards the end of the novel, Harry, Ron, and Hermione confront Sirius and Harry nearly kills him; however, Lupin's timely intervention stops Harry. Lupin, who has learned that Sirius is innocent, is reunited in friendship with him. Pettigrew is unmasked, and, most importantly, Harry stops Sirius and Lupin from murdering Pettigrew, arguing that his father would not want his friends to commit murder. Harry begins to view Sirius as a surrogate father, although events swiftly turn against him again – Pettigrew escapes, and Sirius is captured by the dementors at Hogwarts and sentenced to the Dementor's Kiss, a fate worse than death. Harry and Hermione help him escape with
Buckbeak, a
hippogriff who had also been unjustly condemned. Sirius is once again a wanted man.
Harry Potter and the Goblet of Fire Sirius flees Europe to escape from the
Ministry of Magic. There, he slowly recovers from his years in Azkaban and regains his health. Although he can only communicate sparingly with Harry by
owl post, he gives Harry reasoned and sensible advice. Harry grows closer to Sirius and relies on his help. Sirius, worried, returns to Britain when Harry tells him that his scar has begun hurting him again (a signal of Voldemort's presence), and when there are reports of
Death Eater activities at the
Quidditch World Cup. He sacrifices some of his regained health to help Harry; by the time he reaches Hogsmeade, he is once again gaunt and dishevelled, hiding in a cave with Buckbeak and surviving mainly on rats (with occasional gifts of food from Harry, Ron, and Hermione). He is later summoned to Hogwarts by Dumbledore and listens to Harry's re-telling of Voldemort's rebirth. Dumbledore tasks him with alerting Lupin,
Arabella Figg,
Mundungus Fletcher, and other members of the Order of the Phoenix, and is instructed by Dumbledore to lie low at Lupin's for a while. Sirius reassures Harry, who does not want him to leave, that they will see each other again soon and then departs.
Harry Potter and the Order of the Phoenix Sirius takes refuge in his family home at
Number 12, Grimmauld Place. As the last Black, Sirius inherits the property and allows it to be used as the Order headquarters, although it has fallen into disrepair. Due to the ongoing manhunt, Sirius is confined there. His confinement causes depression, and he is frequently withdrawn and antagonistic – especially so by Snape's increasingly important role within the Order. The hostility between himself and
Kreacher, his demented house-elf, also affects him, and he is consistently hateful towards Kreacher. When he briefly leaves the house to see Harry off to Hogwarts, his Animagus form is recognised by Draco and
Lucius Malfoy, resulting in more threats and warnings. Harry and Sirius stay in touch through owls and the
Floo Network, a system to communicate through fireplaces. Sirius is nearly captured by
Dolores Umbridge, a Ministry official who is monitoring the Network and the owl mail in and out of Hogwarts. Near the middle of the novel, a large number of Death Eaters, including Sirius's cousin
Bellatrix, escape Azkaban. The Ministry, which refuses to accept that Voldemort has returned and that the dementors have joined him, tries to blame Sirius, stating that he helped the prisoners escape and is leading them. Sirius encourages Harry to oppose Umbridge and her reforms and strongly approves of Harry starting the secret defensive tutorial group for students, Dumbledore's Army. He also willingly answers Harry's questions about the Order and Voldemort. Lupin and
Molly Weasley express disapproval for Sirius's behaviour around Harry, stating that Sirius treats his godson as if he is James, Harry's father, and that this is inappropriate. Voldemort plants a false vision in Harry's mind that shows Sirius being tortured at the
Department of Mysteries. Harry and his friends rush to the Department, where they are ambushed by Death Eaters. Meanwhile, Snape alerts the Order that the students have gone to the Ministry. The Order immediately sends a rescue team including
Remus Lupin,
Nymphadora Tonks,
Alastor Moody, and
Kingsley Shacklebolt. Sirius, desperate for any time out of his confinement, comes along too. The Order battles the Death Eaters in the Department of Mysteries. During a frenzied duel with Bellatrix, Sirius taunts her for failing to harm him. Bellatrix strikes Sirius with a curse, sending him backwards into the veil and to his death. Later, Dumbledore persuades the Minister that Sirius is innocent. By the following book, Sirius is exonerated. Dumbledore refers to this as "a brutal ending to what was going to be a long and happy relationship". Harry is left to mourn Sirius, reflecting that, despite his flaws, he was a loving and protective godfather, and the closest thing Harry had ever had to a real parent. Harry inherits all of Sirius's possessions, including the house at Grimmauld Place, the house-elf
Kreacher, and
Buckbeak the Hippogriff.
Harry Potter and the Deathly Hallows Sirius makes his final appearance in
Harry Potter and the Deathly Hallows when Harry discovers the
Resurrection Stone within the golden snitch. Appearing as a ghostly figure alongside Lily, James and Lupin, Sirius supports Harry's walk into death and assures him that dying is, "Quicker and easier than falling asleep." He also promises Harry that the four will always remain a part of him. Rowling revealed a family tree in the J. K. Rowling Documentary on ITV concerning all of the grandchildren of the
Weasley family. In this family tree, it is known that Harry named his first son
James Sirius, after his father and godfather.
Harry Potter prequel Sirius and James are the protagonists of an
800-word story set three years before Harry's birth. The two friends are riding Sirius's motorbike and are chased by two Muggle policemen for breaking the speed limit. The policemen attempt to arrest them when three Death Eaters on broomsticks fly down towards them. Sirius and James use the police car as a barrier and the Death Eaters crash into it. In the end, they escape from the policemen flying on the motorbike. ==Portrayal in films==
