Beware of the Leopard

"But Mr. Dent, the plans have been available in the local planning office for the last nine months."

"Oh yes, well, as soon as I heard I went straight round to see them, yesterday afternoon. You hadn't exactly gone out of your way to call attention to them, had you? I mean, like actually telling anybody or anything."

"But the plans were on display..."

"On display? I eventually had to go down to the cellar to find them."

"That's the display department."

"With a flashlight."

"Ah, well, the lights had probably gone."

"So had the stairs."

"But look, you found the notice, didn't you?"

"Yes," said Arthur, "yes I did. It was on display on the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard.'"
