The Dead Fathers Club

The Dead Fathers Club is a 2006 novel by Matt Haig. The book was published in the United Kingdom by Vintage and in the United States by Viking. The story is a retelling of William Shakespeare's "Hamlet", and thus an example of intertextuality.
Plot summary.
"The Dead Fathers Club" follows the character of 11-year-old Phillip as he is visited by his father Brian's ghost. His father states that he was murdered by his brother Alan and that Phillip must avenge his murder and prevent Alan from taking over the family pub and marrying his widow. Phillip is given three months to avenge his father via the murder of his uncle Alan, lest his father fall prey to the Terrors (the supposed fate for ghosts of murder victims whose deaths are not avenged).
Phillip is encouraged by his deceased father to steal a mini-bus to supposedly prevent Alan from breaking into the pub and is shown several chemicals that could potentially kill his father's murderer. During this time Phillip is assigned to therapy sessions and begins a relationship with Leah, the daughter of a business partner in the garage Alan works at, which Brian does not approve of.
Phillip eventually tries to murder Alan using the chemicals, but he is forced to abandon his first two attempts. In the third attempt, which involves setting fire to his uncle's car garage, Phillip accidentally causes the death of Leah's father. Phillip's conscience eventually leads him to attempt to confess the arson to Leah, who is depressed and slightly delusional at this point. When attempting to confess, Phillip sees the ghost of Leah's father, who attempts to pressure Phillip and make him feel guilty for his acts. Phillip then attempts to confess to Leah's brother Dane, who pulls a knife on Phillip but does not hurt him and instead tells Phillip not to tell Leah about the arson.
Leah later goes missing and Phillip seeks the assistance of other ghosts to find her. Leah is discovered as she is preparing to jump off a bridge, the words "dead and gone" written on her arms in blood. Despite Phillip’s pleas, she jumps and Phillip jumps in after her in an attempt to rescue her. The pair are swept along the water, but are pulled out by Alan and one of his coworkers.
Phillip is taken to the hospital where he discovers a news article that suggests that his father's ghost was lying. Phillip's father is still visible and still attempts to persuade Phillip to murder Alan, who chooses not to listen to his father. Alan eventually dies due to injuries sustained from Phillip's rescue, but it is left unclear as to whether Brian's ghost was saved from the terrors or was simply a figment of Phillip’s imagination.
