command. Flutes and lyres, cymbals and drums,
were heard from the trellised tavern arbors and cook-shops along the
way; and from the little temple to Aphrodite, where Melissa had promised
to meet the Roman physician next morning, came the laughter and song of
unbridled lovers. As a rule, the Kanopic Way was the busiest and gayest
street in the town; but on this night the street of Hermes had been the
most popular, for it led to the Serapeum, where Caesar was lodged; and
from the temple poured a tide of pleasure-seekers, mingling with the
flood of humanity which streamed on to catch a glimpse of imperial
splendor, or to look at the troops encamped on the space in front of the
Serapeum. The whole street was like a crowded fair; and Alexander had
several times to follow Agatha and her escort out into the roadway,
quitting the shelter of the arcade, to escape a party of rioters or the

and escort her to the lake. Agatha thanked him warmly. At this a storm
of rage blew Alexander's self-command to the four winds, and, before he
knew what he was doing; he stood between the rascal and the Christian
damsel, snatched their hands asunder, gripping Castor's wrist with
his strong right hand, while he held Agatha's firmly in his left, and
exclaimed:

"You are being foully tricked, fair maid; the woman, even, is deceiving
you. This fellow is a base villain!"

And, releasing the arm which Castor was desperately but vainly trying to
free from his clutch, he snatched off the false beard.

Agatha, who had also been endeavoring to escape from his grasp, gave
a shriek of terror and indignation. The unmasked rog
