en care not to return the
Englishman's weapon, and there was nothing for Renwick to do but sit in
silence by the side of the melancholy Colossus, and pray for an
opportunity which never came, for Linke had a watchful eye and sat in
the tonneau of the machine. Toward midnight they reached Vinkovcze,
where they had supper, and resumed their leisurely journey with a new
supply of petrol, which only seemed to increase the trouble in the
carburetor. It was at this time that an uncontrollable drowsiness fell
upon Renwick. He struggled against it but at last realized that in spite
of himself sleep was slowly overpowering him. As in a haze he saw the
huge figure of Linke beside him lean over, smiling, while a deep voice
which seemed to come from a distance rumbled calmly,

"You are very sleepy, Herr Renwick?"

Renwick dimly remembered muttering a curse.

"You've drugged--cof----"

Then Renwick slept.

When he awoke it was broad daylight. The car was moving smoothly enough
along a good road between two mountains, and at the side of the road a
river flowed in the direction from which the machine had come.

Renwick felt light-headed and rather ill, and it was some moments before
he became conscious of the figure beside him, while he struggled upright
and found his speech.

"Where are we?" he asked.

"Near Duboj, Herr Renwick, where we shall presently eat our supper----"

"Supper!"

"Yes. You have slept the clock around----"

"Ah, I remember," and he turned upon the man with a renewed and quite
futile anger. "You drugged me, you----"

"Softly, my friend," the big man broke in soothingly. "You can do no
good by defaming me."

Renwick shrugged. "You'll pay the score at settling time, nevertheless."

"Perhaps. In the meanwhile I beg you to consider that you are but fifty
kilometers from your destination. Since we passed the Save we have
proceeded with greater rapidity."

But Renwick had sunk into a sullen silence. The huge creature, whom he
had held in such light esteem, had made a fool of him, had reduced him
to the impotence of a child. As his mind cleared, the object of the
man's actions became more involved. Whatever he was, he had succeeded in
preventing Renwick from reaching Sarajevo before the Archduke's party
should arrive, but why he should wish to drug a man who was meeting his
wishes and giving no trouble was more than Renwick could answer. Still
puzzled, he glanced at his watch. It was now five o'clock.
