In the previous episode, Pug was knocked out when lossened cargo fell on him, then Jimmy learned they had been trapped and locked into the cargo hold. Elsewhere, Clark meets Miss Barrington, an English woman who is travelling with her father. He trusts her enough to share his concern over the warnings he recieved about danger onboard. While the two stroll the ship, they hear Jimmy’s call for help. Now the secret of the cargo is learned.
How does it all connect together? A cargo of nitrate, warning notes, and an International passenger list? But wait, there’s still more suspicious behavior that Jimmy uncovers.
