The body was discovered early in the old library wing. Detective Sarah Mills arrived there precisely at seven-thirty this morning. The victim lay sprawled across the polished mahogany reading tables. Blood had already begun to dry in the cold air. Nothing about the scene suggested an ordinary Tuesday morning here. Mills noted three open books beside the dead man's hands. The security cameras had mysteriously stopped recording just before midnight. Someone had left a single white rose on the victim. No one in the building claimed to have heard anything unusual. The librarian swore she had locked every door herself last night. Yet here was a dead stranger, perfectly arranged among forgotten books.
