Dave nudged his chum as, at a turn in the path, the spy came face to
face with a woman clad in a beautiful evening gown.

Raising his hat, and making a courteous bow to the woman, who returned
the greeting, Gortchky exchanged half a dozen sentences with her. Then
the pair separated, though not before Dave and Dan had obtained, under
the electric light, a good view of the young woman's face. Her dark
beauty, her height and grace, gave her a queenly air.

Stepping into another path, Dave and Dan were soon on the trail of
Gortchky once more, without having been obliged to pass the young
woman face to face.

"I wonder if she's a 'spy-ess'?" murmured Dan.

"It is just as well to be suspicious of any one whom Gortchky appears
to know well," Dave answered, slowly, in a low voice.

"I beg pardon, sir," broke in a sailor from the "Hudson," stepping
forward and saluting the officers. "May I speak with you, sir?"

It was Dan to whom he spoke, and it was Dan who answered:

Martin was one of the gun-pointers in Dalzell's division.

"Linton, one of our men, has been hurt, and rather badly, by falling

"Lead the way, Martin, and I'll follow you. Dave, you'll excuse me for
a little while, won't you?"

"Certainly," nodded Ensign Darrin. Dave wished to remain where he was,
in order to keep an eye over Gortchky's movements, and Dan knew it. So
the chums parted for the present.

"Now, I'll see if I can pick up Gortchky again," reflected Ensign
Darrin. "He appears to have given me the slip."

Dave went ahead, more briskly than he had been moving before, in the
hope of sighting the spy.

Out of the Casino had staggered a young man, despair written on his
face, hopelessness in his very air. Plunging into the garden this
stranger made his way hastily through it, keeping on until he came to
the field where pigeon shoots are held from time to time.

Dave, at the edge of the garden, saw the young man step past the
shrubbery and go on into the darkness beyond. Under the last r
