About the Series

Young detectives. Real mysteries. Unforgettable adventures.

What are the Agent 5 Mysteries?

The Agent 5 Mysteries are a series of mystery and adventure books for young readers aged 8–12. Each book is a self-contained mystery — full of twists, clues, and moments where the reader can piece things together alongside the hero.

These aren’t your average adventure stories. They’re smart, exciting, and written to make readers think. Every mystery is fair — all the clues are there. The question is whether you can spot them before the reveal.

Who writes them?

The Agent 5 Mysteries are written under the pen name M.H. Blackwood — a name chosen to honour the tradition of great mystery fiction. The stories are crafted with care, warmth, and a deep love of reading — especially for young readers who are discovering the joy of a really good mystery for the first time.
