A non-fiction human body detective series about the microscopic crime-solving team in all of our bodies, packed full of easily digestible facts!

Join a team of quirky characters that live in the human body as they investigate the clues behind mystery symptoms to find each culprit to illnesses and ailments.

The Diagnosis Detective Agency work out what’s wrong inside their human body by investigating symptoms and inspecting suspects, before revealing the culprits causing tummy trouble.
Ben Elcomb had a successful career working in television production on a variety of shows including ITV’s This Morning, Britain’s Got Talent and Ministry of Mayhem, and the BBC’s reboot of The Basil Brush Show, Ben branched out into writing scripts for CBeebies’ Something Special. He has written non-fiction books for children, including two books in Flying Eye’s Eva Beaver series (How to Build a Pyramid/Skyscraper) and StemVille: The Bee Connection and The Fast Lane. Also, he wrote Operation Ouch – The HuManual, a companion book to the multi-BAFTA winning CBBC show Operation Ouch. As a father of two children, Ben continues to pursue his passion for writing entertaining and informative works for young audiences.

Terri Po grew up in Hong Kong and studied illustration at the University of Edinburgh, and now lives and works from a wooden cabin in the countryside. She likes drawing anything blobby, including but not limited to: brains, intestines and liverworts.
"A tiny, powerful investigative team of body cells uncover the mystery of a young girl's gastrointestinal illness in Tummy Trouble, the first title in Ben Elcomb and Terri Po's delightfully engrossing nonfiction picture book series Diagnosis Detectives. [...] The book's winning treatment of clear, accurate data and a lighthearted whodunit plot provide plenty of opportunity for discovery and DIY activities offer a fun way to engage with the material, like using glitter to model the transference of food particles."
— Shelf Awareness STARRED Review

"Invaders and protectors face off in the human digestive system. Po’s artwork combines imagination with accuracy; the central players are portrayed both as they appear under a microscope and in their blobby, cartoonish forms. [...] A STEAM winner, sure to inspire future physicians—and reassure young hypochondriacs."
