His word made me vaguely uneasy, for I knew of nothing to take Sadie out that morning, and she was very scrupulous about letting me know before embarking on anything new. However, there was nothing to do until I heard from her.

I plunged into the work awaiting me. That was considerable. I am only giving you an occasional report or part of a report which helps on the story a little. There were dozens of other lines we were obliged to follow that never returned us anything for our work. The office end of my business is the part I like least.

At noon I called the other office again. Sadie had not come in, said Keenan, nor had she sent any word. I was downright anxious by this time. Sadie must know that I would call her up, I told myself. Surely she would never stay away so long without sending in word, unless she were prevented. I called up her sister with whom she lived. They had not heard from her there since she had left as usual that morning.

I spent a horrible afternoon, condemned to inaction, while my brain busied itself suggesting all the dreadful things that might have happened. Curiously enough I thought only of the ordinary accidents of the streets. The truth never occurred to me.

The blow descended about half-past four. Terrible as it was it was like relief to hear anything. It came in the form of a special delivery letter, mailed as in irony from Station W. Within were two lines more of that damned cryptogram, thus:

SP JAH FUXLJG QCXQ WYE DFB&U OWK-
MZM&YW SY EUS UYHJL FVDH QMWZCDBK
QBC OYFG YB UOWX.

Meaning:

"If you return what you stole yesterday in the first mail to-morrow all will be well."

On the back of the paper was written another message:

"They have got me, Ben. Save me!"
