When we last saw Clark, he and Jimmy were staying over at a hotel. It was a ruse from the Yellow Mask and the mystery woman to stop them from getting away with the jewels. By the time they learn things aren’t right, the jewels have again been stolen by the Yellow mask. With a hot story on their hands, Clark and Jimmy set out after the Yellow Mask, and try to catch up with him.
They’re back on the train, but will their sneaking around get Clark and Jimmy any closer to the jewels? What ties does the mystery woman have with the Yellow mask, and is she still working with him?
