The Barker and Llewelyn series by Will Thomas follows private enquiry agent Cyrus Barker and his assistant Thomas Llewelyn through 1880s London. Starting with Some Danger Involved in 2004, the series takes on a new case with each installment, from anarchist bomb plots to Chinatown gang wars to royal conspiracies.
With seventeen books spanning over twenty years, this is one of the more substantial Victorian mystery series around. Thomas keeps the period details grounded without drowning readers in historical exposition. The dynamic between the gruff, secretive Barker and the more relatable Llewelyn gives the books their backbone. New readers should start with Some Danger Involved and work through in order.
