While also having a teenage protagonist and featuring guns, fights, international criminals, and numerous character deaths, The Diamond Brothers series has a more humorous slant through the use of puns, pop culture references and absurd situations.
Tim is somehow framed for the crime, his much smarter and younger brother Nick gets the box of Maltesers, and every crook in town is out to get them.
Meanwhile, Tim has been hired to find a Ming vase called the Purple Peacock that has been stolen from the British Museum, whilst also having to help Nick and Johnny break out of prison.
[3] In The Diamond Brothers in… Where Seagulls Dare (2022), set three months after the events of The Blurred Man, a glamorous woman hires the Diamond Brothers to find her missing father, but they are quickly caught up in a case involving bike-riding hitmen, superhackers and a sinister far-right organisation called the White Crusaders.
The promotional blurbs of the early 2004 editions of the Alex Rider novel Scorpia, and of an early edition of Three of Diamonds claimed that Horowitz was planning an Australian-based adventure for the Diamond Brothers, entitled The Radius of the Lost Shark (a play-on-words on the film title Raiders of the Lost Ark).
Nick then hints that he might one day write down what happened during their visit to Australia and that he might end up calling the book The Radius of the Lost Shark.
[7] In March 2015, Horowitz then stated in a newspaper interview that there would be at least another six books written by him before continuing The Diamond Brothers series.
[8] In December 2015, when responding to a fan query on Twitter regarding the plot of the book, Horowitz revealed that the story would be set during the Australian summer, and that it may involve the characters celebrating Christmas in July.
[10] In April 2020, when the fourth full-length Diamond Brothers novel Where Seagulls Dare was announced, it was initially assumed that the novel would have some relation to the Australian-based adventure alluded to at the end of The Greek Who Stole Christmas, but Horowitz quickly confirmed on Twitter that this was not so, and that The Radius of the Lost Shark has still yet to be written.
Both McLinden and Dale reprised their respective film roles, which makes the television series act as a sequel to Just Ask for Diamond.
