Diagnosis Detectives

Invaders and protectors face off in the human digestive system. Pale-skinned, red-haired young Sophia's down for the count with a stomachache. Elcomb and Po offer readers an up-close look at the causes of-and solution to-her ailment. First, the members of the Diagnosis Detectives Agency are introduced: anthropomorphized T-cells, B-cells, monocytes, and neutrophils, the white cells that make up the body's immune system. Next, we meet the bacterial and viral opposition, led by evil Queen Tox, a menacing blue creature clad in a red crown and dress. All are nicknamed and profiled, but depicted realistically when it comes to unpacking their effects on the body. Most chapters detail the various causes of digestive distress, among them norovirus, food intolerance, and food poisoning, as well as symptoms such as diarrhea, fever, and vomiting. The book concludes by identifying the culprit in this case and describing Sophia's recovery. Relying on the conventions of detective procedure makes for a satisfying plot frame as suspects are listed (with accompanying "mug shots") and the outbreak solved. 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. Insets allow readers to pinpoint the location of the actions, while larger images depict close-ups of the adversaries going at it. Age-appropriate art and science projects are interspersed, along with an "I spy" page. A STEAM winner, sure to inspire future physicians-and reassure young hypochondriacs. * Kirkus Reviews *
This whimsical medical mystery features a team of four detectives (a T-cell, a B-cell, a monocyte, and a neutrophil) attempting to determine what's making a young human, Sophia, feel so gross. Introductory content explains how cells, as part of the body's immune system, come together to fight antigens, whether viruses, toxins, or bacteria. At each stage of Sophia's symptoms (feeling tired, vomiting, diarrhea, fever), the detectives conduct on-site visits throughout her intestinal tract, collecting evidence and creating hypotheses. Various causes are considered: food poisoning, allergies, gastroenteritis; eventually, the culprit is revealed: a norovirus. The cartoon illustrations seem designed for a young audience, and Sophia appears to be around six; the text seems geared towards an older audience, and some readers may have difficulty switching between the straightforward informational text and the goofy adventures of our stalwart heroes and their nemeses. Despite these quibbles, kids tend to be fascinated by all aspects of the human body. This STEM selection offers reliable facts, accessible explanations, and relatable scenarios. -- Kathleen McBroom * Booklist Review *
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. -- Kieran Slattery * Shelf Awareness STARRED Review *
The science content in this book is aspirational, explaining different antigens and immune system reactions in detail and with the correct terminology. This information is complemented superbly by fun characters and brilliant, immersive illustrations which bring the inside of the body to life and add context and anatomical clarity. Featuring DIY science experiments, tons of clear information, and excellent anatomical illustrations, this would be a perfect book to use alongside Key Stage 2 science topics on the human body, or for more general health and hygiene topics in PSHE sequences. * BookTrust *
The story highlights symptoms and possible health problems, helping readers to develop the vocabulary to describe symptoms and also the concepts of cause and effect. The language used is not overly medical, but informative enough for the reader to know when to tell their adult they are not feeling well and to be self-aware enough to know something doesn't feel right. Awareness of personal hygiene and the connection to taking ownership of their own health risks is very impactful. The section on food intolerances will also support the readers in discussing their own issues, but also encourage empathethy towards others who do have these intolerances. An engaging read from the very start. -- Jane Burns * Children's Books Ireland, Our Recommendations *
