But that proved nothing, for even the door sounded equally solid; the folk who built that palace used solid timber, not veneer, and as I found out afterward the door was nearly a foot thick.

On the floor I could make no impression whatever by thumping, and there was no furniture except the pillows--nothing that I could use for a weapon.
But there were the cotton ropes with which they had bound me, and before doing anything else I knotted them all into one.

I had no particular reason for doing that beyond the general principle that one long rope is usually better than a half-a-dozen short ones in most emergencies.
There was only one window, and that was perhaps two feet high, big enough, that is, to scramble through, but practically inaccessible, and barred.

The only weapon I had was that infernal brass safety-pin that had held the towel to my scalp, and I stuck that away in my clothes like a magpie hiding things on general principles.
I began to wonder whether it would not be wisest after all to lie down and sleep.

But I was too hungry to sleep, and it was recognition of that fact which produced the right idea.
Beyond doubt Yasmini realized that I was hungry.
