You hadn't exactly gone out of your way to call attention to them had you? I mean like actually telling anyone 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 torch.
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 in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying "Beware of The Leopard".
