Born:
April 5, 1955, Stanmore, Middlesex, England (age 70)

Anthony Horowitz (born April 5, 1955, Stanmore, Middlesex, England) is a prolific British author and screenwriter known for his popular young adult fiction. Horowitz has also written for an adult audience and has created and written several television shows that were originally telecast in Great Britain but have since been shown in other countries.

Horowitz was born in Stanmore, Middlesex (now in Greater London). After deciding at an early age that he wanted to be a writer, he studied English literature and art history at the University of York in England (1977) to further that goal. He published his first book, The Sinister Secret of Frederick K. Bower (also published as Enter Frederick K. Bower), a children’s adventure story, in 1979. In the early 1980s Horowitz concentrated on writing books for the Pentagram series, which included The Devil’s Door-bell (1983), The Night of the Scorpion (1985), The Silver Citadel (1986), and Day of the Dragon (1989). These science fiction books revolve around characters who fight against an evil that threatens the world. The books did not sell well, however, and Horowitz never wrote the fifth and final story of the series.

In the 1980s Horowitz also began his Diamond Brothers series, which relates humorous stories about an inept 20-something private detective and his teenage sibling who actually solves the cases. Aiming for a preteen or young teen audience, this series includes both full-length novels and shorter novellas with titles such as The Falcon’s Malteser (1986), South by South East (1991), and The Greek Who Stole Christmas (2007). The first book appeared as a film, Just Ask for Diamond, in 1988. Simultaneously, Horowitz published Groosham Grange (1988), about a teenage witch who is dissatisfied at boarding school. In 1999 a sequel, The Unholy Grail (republished as Return to Groosham Grange, 2003), was published.

Horowitz began the 21st century by releasing the first of his Alex Rider novels. This series starts with the main character, a 14-year-old boy, being blackmailed into joining MI6, the British Secret Intelligence Service. Each book places Alex in dangerous yet thrilling spy situations. The first book in the series, Stormbreaker (2000), was made into a film titled Alex Rider: Operation Stormbreaker in 2006, with Horowitz writing the screenplay. Other titles in the Alex Rider book series include Eagle Strike (2003), Snakehead (2007), and Scorpia Rising: The Final Mission (2011).

Beginning in 2005, Horowitz started publishing books for the Power of Five series (called the Gatekeepers in the United States). These novels were updated, revamped versions of the Pentagram series. Starring five teenagers trying to save the world from being destroyed, these books blended pulse-pounding action sequences reminiscent of the Alex Rider series with supernatural elements including witches and demons. The Power of Five books, which began with Raven’s Gate (2005) and ended with Oblivion (2012), gained popular and critical acclaim.

In addition to writing young adult novels, Horowitz is an accomplished writer in other genres. He was involved with numerous television shows since the 1980s, most notably the murder mystery Murder in Mind, the crime drama Collision, and the detective drama Foyle’s War, all produced in the early 21st century. His horror film, The Gathering, starring American actress Christina Ricci, was released in 2002, and his play, Mindgame (2000), debuted in New York City in 2008.

From the 2010s to the 2020s, Horowitz focused on publishing adult fiction. He was commissioned to write continuation novels in popular series, including the Sherlock Holmes novels The House of Silk (2011) and Moriarty: A Novel (2014) as well as the James Bond novels Trigger Mortis (2015), Forever and a Day (2018), and With a Mind to Kill (2022). Horowitz also began his Susan Ryeland mystery series, about an editor who becomes involved in murder mysteries. The first book in the series, Magpie Murders (2016), gained critical acclaim and was serialized on TV in 2022. A sequel, Moonflower Murders, was published in 2020. Horowitz featured a fictionalized version of himself in his Hawthorne and Horowitz mystery series, which centres on a private investigator, Daniel Hawthorne, solving murder mysteries with Horowitz as his sidekick. He began the series with The Word Is Murder (2017); other titles in the series include The Sentence Is Death (2018), A Line to Kill (2021), and The Twist of a Knife (2022).

Joan Hibler The Editors of Encyclopaedia Britannica

murder, in criminal law, the killing of one person by another that is not legally justified or excusable, usually distinguished from the crime of manslaughter by the element of malice aforethought.

The term homicide is a general term used to describe the killing of one human being by another. A murder is considered a homicide, but homicide can also refer to a killing deemed justifiable or excusable. All legal systems make important distinctions between types of homicide, and punishments vary substantially according to the killer’s intent, the circumstances of the homicide, and other factors.

Common-law codes define murder as a homicide committed intentionally or as a result of the commission of another serious offense. By contrast, the crime of manslaughter includes killings that are the result of recklessness or violent emotional outbursts. Penalties for murder are substantially more severe than those for manslaughter and may include capital punishment or life imprisonment.

Common-law systems require an element of intent (malice aforethought, or mens rea) in order to classify a killing as a murder. This includes “transferred intent”—as when one who intends to kill another kills a third person by mistake—and intent that may be inferred from the extreme recklessness or dangerousness of the act. Many U.S. states distinguish between murder of the first, second, and third degree, with capital punishment limited to crimes of clear intent.

Civil-law codes group all unjustified killings under the single crime of homicide. Penalties are determined based on the circumstances of the act, and they vary across countries. Civil law of the European tradition, like common law of the Anglo-American tradition, distinguish between intentional and other felony murders on the one hand and reckless, negligent, and provoked murders on the other. In all systems, the most important distinction relevant to sentencing is that between conduct that is socially dangerous—that demonstrates intent to kill, in other words—and conduct that is merely reckless.

Civil-law codes also place a greater emphasis on the dangerousness of the killer’s conduct and the circumstances surrounding the act. Bodily injury that results in death as well as a death that is the result of negligence rather than recklessness are two examples of homicides that are more heavily penalized in civil-law systems than in common-law ones. Civil-law codes often punish any killer as a murderer if the culprit has employed a deadly weapon, but in England, for example, death resulting from a felony is defined as murder only in the case of certain serious crimes, such as robbery or rape.

The terms serial murder and mass murder refer to the unlawful homicide of multiple people by the same person. Definitions of these terms are debated, and neither are formally recognized in legal codes. These murders, and the people who commit them, generate tremendous amounts of public attention. Mass shootings, when fatalities occur, are a form of mass murder. Assassinations are a particularly high-profile type of murder.
