"In the hall, governor! I never left the hall for a second! I should
have seen her go out, blow it!"

"Still, she's not here now..."

"So I see," moaned the man, quite flabbergasted.

"She must have got tired of waiting and gone away. But, dash it all, I
should like to know how she got out!"

"How she got out?" said Lupin. "It doesn't take a wizard to tell that."

"What do you mean?"

"She got out through the window. Look, it's still ajar. We are on the
ground-floor... The street is almost always deserted, in the evenings.
There's no doubt about it."

He had looked around him and satisfied himself that nothing had been
taken away or moved. The room, for that matter, contained no
knick-knack of any value, no important paper that might have
explained the woman's visit, followed by her sudden disappearance.
And yet why that inexplicable flight?

"Has any one telephoned?" he asked.

"No."

"Any letters?"
