"A cross was drawn at the crime scene."
Interpretation of the clue:
Warning road signs are placed immediately before a railway crossing:
For a single-track railway, this sign is in the form of a cross; for a multi-track railway, it is in the form of a cross with an inverted checkmark under the cross.
Initially, I wanted to reject the clue because it seemed too far-fetched, but I still left it in.
Anyone who drives across railway crossings should understand this. And there's no need to look it up in a wiki.

В тихой однообразной жизни всегда так бывает: каждый отдельный день бесконечно долог, но месяцы и годы мчатся с непостижимой быстротой.
