You're a blockchain sleuth trying to track down a rogue developer who disappeared with a wallet holding 500 BTC. You’ve narrowed it down to 3 suspects, all ex-devs from the same project.
Each suspect gives a statement — but only one tells the truth, the others are lying.
🧍 Suspect A says:
"I didn't take the key. Suspect B did."
🧍 Suspect B says:
"Suspect C stole the key."
🧍 Suspect C says:
"I didn't steal anything. Suspect A is lying."
