But it did not stay there. I saw a sudden change creep over the man's face. He looked up with a quick and bird-like side-movement of the head. It was not until he wheeled about that I realized the reason of the movement.

The actual motive behind the thing I could not fathom. The real significance of the tableau was beyond my reach. But as I looked up I saw that the woman had crept noiselessly to the hall door, and with a sudden movement had thrust out her hand and tried to open this door. But as I had already locked it, and still carried the key in my pocket, her effort was a useless one. Just why it should enrage her confederate was more than I could understand. He ignored me for the time being, crossing the room at a run and flinging the woman in black away from the door-knob. She, in turn, was making a pretense to resent that assault. Why she should do this I did not wait to ask. I saw my chance and took it.

Half-a-dozen quick steps brought me to the bathroom door, one turn of the knob threw it open, and another step put me through it and brought the door closed after me. There was, I found, a key in the lock. Another second of time saw that key turned. A quick pad or two about the cool marble wall brought my hand in contact with the light-switch.

The moment the light came on I darted to the inner door and tried it. But this, to my dismay, was locked, although I could catch sight of no key in it. I ran back for the key of the first door, tried it, and found it useless. At any moment, I knew, a shot might come splintering through those thin panels. And at any moment, should they decide on that move, the two of them might have their own door into the hallway forced open and be scampering for the street.

I reached over and wrenched a nickeled towel-bar away from the wall opposite me. One end of this I deliberately jabbed into the white-leaded wood between the frame and the jam of the second door. I was about to pry with all my force, when the sound of yet another voice came from the room before me. It was a disturbed yet sleepy voice, muffled, apparently, by a second portière hung on the outside of the second door.

"Is that you, Simmonds?" demanded this voice.

I continued to pry, for I felt like a rat in a corner, in that bald little bathroom, and I wanted space about me, even though that meant fresh danger. The mysteries were now more than I could decipher. I no longer gave thought to them. The first thing I wanted was liberation, escape. But my rod-end bent under the pressure to which I subjected it, and I had to reverse it and try for a fresh hold.

I could hear, as I did so, the sudden sound of feet crossing a floor, the click of a light-switch, and then the rattle of the portière-rings on the rod above the door at which I stood.

"Who locked this door?" demanded the startled voice on the other side. For answer, I threw my weight on the rod and forced the lock. I still kept the metal rod in my hand, for a possible weapon, as I half-stumbled out into the larger room.

Before me I saw a man in pajamas. He was blond and big and his hair was rumpled—that was all I knew about him, beyond the fact that his pajamas were a rather foolish tint of baby-blue. We stood there, for a second or two, staring at each other. We were each plainly afraid of the other, just as we were each a little reassured, I imagine, at the sight of the other.
