The Mystery Agency returns with a brand new escape-room style puzzle solving mystery for all ages! Perfect for fans of Murdle and an Agathe Christie story.

London, April 1929. As the sun rises one crisp spring morning, it reveals a body lying in the centre of

Bookseller's Row, a narrow alleyway in the West End famed for its bookshops.

D.I. Waterstone soon arrives on the scene and discovers the body belonged to James R.

MacMillan, a property developer who planned to level Bookseller's Row to build luxury apartments. It appears every shop keeper on the street had motive to murder MacMillan, but who committed the crime?

Put yourself to the test, and follow the story, working your way through a whole host of challenges - from deciphering clues at crime scenes and searching for hidden pieces of evidence in the pages - to satisfy your inner detective. Can you step into the Detective Inspector's shoes and solve the case?

Praise for The Mystery Agency

'I loved this book! Highly recommended' - Matt Lucas, Actor and comedian

'I'm just mad about the Mystery Agency, and even madder about Henry Lewis. Like, it makes me actually mad how wonderfully talented he is at puzzle creation and storytelling. This book is an utter delight, one that should be in the collection of any sharp thinker. I hated how much I loved it. Can't recommend it enough.' - Neil Patrick Harris, puzzle-master and award-winning actor
