The Chinese Orange Mystery (1934)

An unidentified visitor is killed in a publisher's waiting room, where the arrangement of objects has become bizarrely wrong. Ellery Queen's investigation rewards an inventory of what the room contains and what witnesses can establish. The solution is elaborately constructed, so choose this for the pleasure of a formidable artificial puzzle rather than everyday plausibility. Its physical detail and deliberate reader challenge make it good territory for a patient diagram-maker.
