Just the Facts, Ma’am by Greg Fallis is a crime-writer’s reference on private investigation and detective work, written by a former private investigator who knows the real job rather than the television version of it. For mystery, crime, and thriller writers featuring investigators, professional or amateur, it supplies the authentic procedural detail that separates a convincing detective story from one that recycles screen clichés. As one of the better-regarded crime references, it does its specialized job well, with the now-familiar caveat about its age.

The lens, as with all these references, is craft: the value is authentic detail for writing believable fiction, and this review treats it as that tool. The real-investigator authorship is the heart of its appeal.

The real job, not the TV version

The book’s central value is correcting the gap between fictional and actual investigation. Real detective work, Fallis shows, is far less glamorous and far more methodical than its screen portrayal, the patient legwork, the records and databases, the interviews, the surveillance, the dead ends, and the legal and practical limits on what an investigator can actually do. Using real-life scenarios, he shows writers how investigative professionals genuinely operate, so a writer can build a detective whose methods ring true to anyone who knows the work. For the many writers whose sense of investigation comes secondhand from crime drama, this reality check is exactly what keeps a mystery credible.

Professional and amateur both

A useful feature is the book’s attention to how both professional and amateur investigators would realistically work, which matters because mystery fiction is full of amateur sleuths, and a writer needs to understand what an untrained person could plausibly discover versus what requires professional access and method. Fallis’s real-world grounding helps a writer calibrate this, keeping an amateur detective’s deductions within the bounds of believability while giving a professional the authentic techniques of the trade. That distinction between what different kinds of investigator can plausibly do is a subtle but important aid to credible plotting.

The currency caveat

The standard limitation applies. The book dates from the 1990s, and investigation has changed enormously since, especially in the tools available: digital records, online databases, social media, cell-phone data, and surveillance technology have transformed how investigators, professional and amateur, actually work. The fundamentals of methodical investigation, legwork, interviews, logic, the patient assembly of facts, age well, but the technological specifics are substantially dated, and a writer setting a contemporary story must update the methods against current practice. The book grounds the timeless craft of investigation; it cannot speak to the digital tools that now dominate it.

Verdict

It is a solid, authentic crime-writer’s reference on investigation, valuable for its real-investigator perspective on how detective work actually happens and its useful attention to both professional and amateur sleuths, the kind of grounding that keeps a mystery credible. It loses ground for its 1990s vintage, which dates the technological side of investigation significantly in an era transformed by digital tools, so the methods need updating for a contemporary setting. Treat it as authoritative on the timeless fundamentals and a starting point on the specifics, useful to the crime writer who wants their investigator to ring true. A capable reference, dated in its tools like its shelfmates.
