Last Seen: Casefile Anomalies examines fifteen unresolved cases through a disciplined, evidence-first lens. Built from public records, archives, contemporaneous reporting, and careful reconstruction, this volume does not chase sensational answers or force theories where the record does not support them. Each casefile is treated as a ledger: what is known, what conflicts, what remains missing, and what can still be tested. Inside are cases involving vanished lighthouse keepers, unidentified bodies, impossible placements, anonymous letters, unexplained deaths, missing children, aviation mystery, environmental failure, and crimes where the evidence refuses to settle into one clean shape. K.G. Groves approaches each case with restraint, separating documented facts from later myth, rumor, and speculation. The result is not a book of easy conclusions. It is a study of what remains when the record stays open. For readers of true crime, historical mysteries, cold cases, and investigative nonfiction, Last Seen: Casefile Anomalies offers a sober, atmospheric, and deeply structured look at cases that still ask for patience.
