court-yard he shivered. He was not cold, though this was
Siberia--Vladivostok--and a late winter night. But he was excited.

Before him, slipping, sliding, rolling over and over on the hard packed

for the upper hand. The clock in the Greek Catholic church across the
way told Johnny how long they had fought.
