Summary:
Alec tracks the unknown men at the railroad; a second body is uncovered.
After giving the situation some thought, Alec comes up with a likely profile. Men who know each other, who've had dealings, and who will travel together when they won't risk being sighted - or travel separately to avoid raising suspicion. Men with a purpose, and a schedule, who came and left deliberately. There will be many marks on the ground, but he hopes that few will satisfy those criteria.
