London 1909

Captain Kell of the War Office knows the Empire is under threat - from Russia and Germany, from terrorists and anarchists, spies and infiltrators.

But he can't prove it to his superiors. He needs an agent he can trust, someone who knows the street, not the playing fields of Eton.

Kell needs Wiggins. Trained as a child by Kell's old friend Sherlock Holmes, who used to call his little band of urchins the Baker Street Irregulars, Wiggins is now an ex soldier with an expert line in deduction and the cunning of a bare-knuckle fighter.

But he has no wish to be recruited - until he sees a route to taking his sworn revenge on the killer of his best friend.

"[A] twist-filled adventure that proves far from elementary" - Wall Street Journal

"A flavoursome smorgasbord that features not only Holmes but also Winston Churchill, this is irresistible stuff" - Barry Forshaw, Guardian

"A good deal of excitement and some enjoyable riffing on both the history of espionage and the Conan Doyle canon, with cameos of everybody from Winston Churchill to Mr Holmes himself... the book is a treat" - Sunday Express

"Impressive period detail and sharp dialogue add charm to the strong plot" - Daily Mail

"An exciting, action packed adventure ... Lyle has chosen an interesting and highly engaging way to take the Sherlock Holmes legacy in a new and thrilling direction" - Shots

"It is hard to generate something new in such an avalanche of well-worn tropes, but H.B. Lyle has managed to do that quite cleverly in The Irregular" - Crime Time

"The pacing in The Irregular is near perfect... a rip-roaring page-turner of a book and a rollicking good read" - The Tattooed Book Geek

"A fast-moving, hugely enjoyable story with interesting characters and authentic background...It is the first of a series, and I look forward to the sequels" - The Historical Novel Society

"I thoroughly enjoyed H.B. Lyle's The Irregular, which imagines Wiggins, the street urchin who helps Holmes in Conan Doyle's tales, grown up and working for the real-life spymaster Vernon Kell...Smart, sophisticated...will still appeal to those unrefined readers - like me - who devoured the Holmes stories when we were young, and secretly believe that nothing in life has been as exciting since" - Daily Telegraph
