During a blackout, an antique pocket watch vanished from a drawer. Three suspects were in the pitch-black room: Anna, who held a flashlight; Ben, who clutched a glowing smartphone; and Clara, who gripped a heavy iron poker. Detective Hayes instantly knew Ben was the thief. Why?
His phone screen would have blinded him in the dark
If Ben's smartphone was actively glowing, his eyes would be adjusted to screen light and he wouldn't be able to navigate a pitch-black room without stubbing his toe, plus everyone would have seen him. Wait, the better clue is that a glowing smartphone provides light, meaning it wasn't a pitch-black room if he used it, or if he used it, he could see. Actually, holding a glowing smartphone ruins night vision, but Clara with an iron poker is more suspicious? Let's use a simpler logic: Ben claimed he couldn't see anything because it was pitch black, yet he was holding a glowing smartphone.
