The book centers on a thrilling detective adventure led by a "rookie investigator," who finds himself confronted with an enigmatic mystery requiring an ingenious solution. The unique feature of this book lies in its reliance on "forensic odontology"—the science of dental evidence—as the means to solve the case. By tracing the "bite marks" discovered at the crime scene, the protagonist (and, along with him, the reader) learns how seemingly minor traces can reveal the identity of the perpetrator.
