In Chapter 9, the investigators gather to remember their fallen comrade, Jim Arnold. But Sakima and Mace are still loose, so they must continue with their relentless pursuit.
In order to photograph a secret truck loaded with a mobile television range finder, which the insurance investigators are guarding, one of the bad guys hides in a trunk which is then delivered to the harbor warehouse containing the truck. When no one is around, he sneaks out and takes his photographs.
But the Masked Marvel shows up and catches him in the act. After knocking out the villain, the Marvel decides to use the trunk to infiltrate Sakima's secret hideout. He stows away in the trunk as two other henchmen come back to pick it up. However, as they are taking it back to their hideout, the photographer gets loose and calls Sakima, warning him of the unpleasant surprise in the trunk.
The villains decide to get rid of the Masked Marvel by opening up the throttle on the delivery truck and running it off the road with the Masked Marvel trapped in the back.
The Masked Marvel tries to get the doors unlocked, but no such luck!!
The truck roars down the road uncontrollably, and finally plunges off a cliff at a high rate of speed. Another sticky cliffhanger for our dauntless hero. How will he survive this time?
