At the end
of Chapter 3, the Masked Marvel had fallen into the elevator shaft from
the 6th floor of the garage. Fortunately for him, Alice had already
started up with the elevator, so he only fell one floor. Meanwhile,
Mace escapes from the garage and finds the diamonds.
In Chapter
4, Sakima decides to use the diamonds as bait in a trap for the Masked
Marvel. He offers to trade the diamonds for cash. Mace and
another bad guy wait behind a one-way mirror while Alice delivers the money
and takes the diamonds.
After Alice
leaves, they set a bomb in a clock, set to go off at midnight. Then
they wait for the Masked Marvel to appear.
The villians
taunt the Masked Marvel through a hidden speaker, but he destroys the mirror,
and a fight ensues. As the fight rages on, the clock strikes midnight.
But
wait! This is not the cliffhanger! The Masked Marvel (and Mace)
easily escape from the house before it explodes. When Mace radios
this information to Sakima, the Japanese agent decides to find out which
of the four investigators is actually the Masked Marvel. He tells
Crane to call of the investigators into the office, and the one who does
not show up is the Masked Marvel.
As the chapter
ends, Sakima announces "So. Jim Arnold is the Masked Marvel."
Is this the end of the Masked Marvel's secret identity?
