e. "Mrs. Jasher would be
spotted in a moment if she had gone to your quarters. She had to pass
the sentry, remember. Then, again, we have not yet proved that she was
the woman in Mrs. Bolton's clothes who spoke through the window. That
can all be settled if we speak to her this evening."

"Very good." Random glanced at his watch. "I must get back. Don Pedro,
will you tell Inez that I shall come in this evening? We can then talk
further about these matters. Hope?"

"I shall stop here, as I wish to consult Don Pedro."

Random nodded and took a reluctant departure. He dearly wished, as an
engaged lover should, to remain on the chance that Donna Inez might
return, but duty called him and he was forced to obey.

The night was very dark, although it was not particularly late. But
there was no rain, and Random walked rapidly through the village and
down the road to the Fort. He caught a glimpse of the lights of Mrs.
Jasher's cottage twinkling in the distance, and smiled grimly as he

it on the floor of the box, sir, when I was at the other end of my beat,
sir. It was as dark as this, sir, and I saw nothing and heard nothing.
When I come back, sir, I stepped into the box out of the rain and felt
it with my feet. I struck a light, sir, and found it was for you."

Sir Frank slipped the package into his pocket and went away after a grim
word or so to the sentry, advising him to be more on the alert. He was
puzzled to think who had left the packet in the sentry box, and curious
to know what it contained. As soon as he got to his own room, he cut
the string which bound loosely the brown paper. Then, in the lamplight,
there rolled out from the carelessly-tied parcel a glorious sea-green
emerald of great size, radiating light like a sun. A scrap
