"You had better kill time for a few minutes," Dave explained to the
chauffeur, who understood English. "It is not desirable to reach the
railway station earlier than 7.20."

Accordingly the young ensign enjoyed a brief, rapid panoramic view of
a considerable part of Paris. The driver, accustomed to taking
Americans about who were strangers in the city, frequently turned his
head to offer information as to the places or points of interest that
they were passing.

"It's a shame that Danny boy isn't here to enjoy all this," Dave told
himself. "Even this way of seeing Paris would be a great treat to
him."

Almost to the second of 7.20 the taxicab drew up as one of a long line
of similar vehicles under the bright lights of the railway station.

Alighting, Ensign Darrin, feeling rather well concealed in his
disguise, and looking out through his blue-lensed eyeglasses, strolled
about, careful not to saunter into the most brilliantly lighted spots.

Presently he heard a train enter the station. A thin stream of

watched the arrivals, who later came out in a more compact throng.

And there was Emil Gortchky, at last, with no more marked hand luggage
than a light cane, which he swung jauntily.

"I hope you don't look my way, my fine bird!" uttered Ensign Darrin
under his breath. "But if you do, your observation won't do you much

A hand beckoned from a taxicab. Emil Gortchky, who had been on the
lookout, sauntered over to the vehicle and clasped the hand of M. le
Comte de Surigny.

"Surigny, the ungrateful!" uttered Dave disgustedly to himself. "I
induced you to spare your own worthless life, and then when you found
life sweet once more, you turned against me! I hope you did not notice
me as you sat in that cab."

By this time Dave was at the side step of his own taxicab. A few words
to the chauffeur, and he entered.

Surigny's cab drew out of the line, gliding away. The one in which
Dave sat gave chase at a cautious distance.

Soon the speed of the leading cab increased, and the pursuing
one followed at the same speed. After a considerable run both
cabs turned into the broad, well-lighted Boulevard Haussman.
For some blocks both cabs ran along. Then the one ahead turned
in before an imposing-looking building with a gleaming white
marble front.

"The Grand Prix Club," explained Dave's chauffeur, glancing bac
