'Khan’s Q proves a highly engaging hero. An unorthodox addition to the Bond canon this may be, but it’s carried out with such wit and gusto that it proves a worthy one.' The Telegraph

'Excellent. An entertaining mash-up of Fleming, Le Carré and the best of British detective fiction' Charlie Higson

'Clever, cunning and quirky... Quintessential Khan.' Mick Herron

'A thrilling addition to the 007 universe... A cracking tale worthy of Fleming himself.' Matt Nixson, The Express

'Khan has crafted a cunning and propulsive thriller brimming with wit. A sparkling addition to Bond's literary universe.' Mark Billingham

Filled with wit and verve, Vaseem Khan brings his vibrant and dynamic style to one of Ian Fleming's most beloved characters, Q. Charming, drily humorous, and intelligently crafted, Quantum of Menace, the first in the Q mystery books, will appeal to Bond fans, readers of Murder Before Evensong, The Thursday Murder Club and Slow Horses novels, and those who are looking for a new take on clever crime fiction.

Q is out of MI6 and into a new world of deceit and death.

After Q (aka Major Boothroyd) is unexpectedly ousted from his role with British Intelligence developing technologies for MI6's OO agents, he finds himself back in his sleepy hometown of Wickstone-on-Water. His childhood friend, renowned quantum computer scientist Peter Napier, has died in mysterious circumstances, leaving behind a cryptic note. The police seem uninterested, but Q feels compelled to investigate and soon discovers that Napier's ground-breaking work may have attracted sinister forces... Can Q decode the truth behind Napier's death, even as danger closes in?

'Bond fans will relish this first outing with Q, a delicious feast of skulduggery, espionage and technological wizardry served up with a side helping of genuine emotional intensity, spine-tingling suspense, some likeable new faces, and welcome cameo appearances from forever favourites like Bond and Moneypenny.' Lancashire Post

'Perhaps more thoughtful, politically aware and emotionally wise than the original, this terrific new series with the inimitable Q at its heart will please both Bond and detective fiction fans.' Yorkshire Post
