'I don't know his name. But he's come, and he's in the bedroom now, with Aunt Susan.'

'How annoying!' said Dr. Quain Short under his breath, and he went.

Tom re-entered, and took up his old position behind the portière.

Presently he heard another step on the stair, and issued out again to reconnoitre. And, lo! another tall gentleman wearing another high hat and carrying another black bag was ascending.

'This makes three,' Tom said.

'What's that, my little man?' asked the gentleman, smiling. It was Dr. Christopher.

'This makes three. And they only want one. The first one came ever such a long time ago. And I can tell you Aunt Susan was very glad when he did come.'

'Dear, dear!' exclaimed Dr. Christopher. 'Then I'm too late, my little man. I was afraid I might be. Everything all right, eh?'

Tom nodded, and Dr. Christopher departed.
