ers of the room and departed. Mr. Prohack continued his
breakfast.

Miss Winstock appeared with a small portable typewriter in her arms and
a notebook lodged on the typewriter. She was wearing a smart black skirt
and a smart white blouse with a high collar. In her unsullied freshness
of attire she somewhat resembled a stage secretary on a first night; she
might have been mistaken for a brilliant imitation of a real secretary.

"Good morning. So you're come," Mr. Prohack greeted her firmly.

"Good morning. Yes, Mr. Prohack."

"Well, put that thing down on a chair somewhere."

Machin also had entered the room. She handed a paper to Mr. Prohack.

"Mistress asked me to give you that, sir."

It was a lengthy description, typewritten, of a house in Manchester
Square.

"Pass me those matches, please," said Mr. Prohack to Mimi when they were
alone. "By the way, why wouldn't you give your name when you arrived?"

"Because I didn't know what it was."

"Didn't know what it was?"

"When I told you my Christian name yesterday you said it wouldn't do at

instructions about my surname I thought I had better pursue a cautious
policy of waiting. I've told the chauffeur that he will know my name in

and I were both in a state of collapse after the accident, and I was
removed before she could see me. Therefore she did not recognise me this
morning. But on the other hand she has no doubt heard my name often
enough since the accident and would recognise _that_."

Mr. Prohack lit the first cigarette of the day.

"Why did you bring that typewriter?" he asked gravely.

"It's mine. I thought that if you didn't happen to have one here it
might be useful. It was the typewriter that the car had to go back for.
I'd forgotten it. I can take it away again. But if you like you can
either buy it or hire it from, me."

The girl could not have guessed it from his countenance, but Mr. Prohack
was thunderstruck. She was bringing forward considerations which
positively had not presented themselves to him. That she had much
initiative was clear from her conduct of the previous day. She now
disclosed a startling capacity for intrigue. Mr. Prohack, however, was
