"Please have Miss Farrell come up-stairs," I said over the phone.

I had one of the best suites at the Rotterdam, a corner room which was my parlour, and a bedroom. I put the key to the parlour door in my pocket, retired into the bedroom, and locked the communicating door. Presently I heard the bell-boy's knock on the parlour door.

"Come in!" I sang out.

Through the door I heard the sounds of two people entering my parlour.

"Hello, Sadie!" I cried. "Make yourself at home. I'll be dressed in a jiffy!"

An indistinguishable murmur answered me. This was certainly not my Sadie.

The bell-boy went out, and I heard him retiring down the hall. I gave him time to get out of the way, then I slipped out of the bedroom into the hall, key to the other room in hand. I inserted it ever so softly in the parlour door, and turned it. But she heard! She rushed to the door and shook it. By that time I was around the corner of the corridor.

The telephone girl looked at me somewhat curiously as I pressed the elevator button, but did not quite like to question me. She knew, of course, that a caller had just been shown into my room.

"I'll be back in a minute," I said carelessly.

Just then I saw the number of my room 1104 displayed on the switchboard. Lorina had rushed to the phone.
