The dockworkers they were following didn't all head to the same place. Andrea figured that whenever there was a split in the group, it made sense to follow the larger part. By the time the group had thinned to just six men, she started to wonder if her plan was going to work, or if they were just going to end up following two guys who went home for lunch.
She glanced behind them. Andrea assumed Steel was probably following them as they followed the dock workers. If so, he was somehow managing to do it unseen. Perhaps he was in his car and using binoculars, moving up occasionally as needed. Despite their game losing him at the market the previous day, he still had more experience than the two of them put together tracking a target unseen.
