An apparently solved Westminster murder leaves one crucial question unanswered. Kiwi, a New Zealand forensic psychologist, looks beyond the obvious suspect to distinguish the person who committed the killing from the person who quietly constructed it.

That Bloody Parcel

The listing is still live. The buyer isn’t.

Four people die after buying four different products through TreLLiVane, a fictional global marketplace. Luc De Peyrac follows the warnings, removals and successor listings to ask what happens when a page disappears but its safety history does not travel with the product.

That Bloody Parcel

Since his own ladder accident, Luc has warned that one day somebody will die. When four apparently unconnected deaths enter four separate investigative systems, he uses H.UN.T—Hunting Unsafe Tech—his human-reviewed system for finding potentially unsafe products through online listings, warnings and successor identities. A ladder, a battery, a magnetic toy and a beauty product appear unrelated. The resulting dossier separates what is known from what has merely been suspected—and discovers that all four warning trails converge on TreLLiVane.

A nurse is charged with murder after babies die in her care. Is she guilty, a convenient scapegoat, or part of a parallel case hiding something much larger?
