When last we left "Death Loads the Bases", Captain America had deduced that a thrown baseball, was in fact, a bomb.
The hissing fuse was probably his first clue. So, exactly who do you hire to replace a pitcher's ball with a bomb, without anybody noticing? Abra Kadabra?!
Anyway, Cap explodes the basebomb with his America-vision, or something. Which has (what I found to be) the very amusing effect (for no apparent reason) of causing the Black Toad to run out into and back and forth in the stadium...
...looking for all the world like the Hooded Claw chasing Penelope Pitstop.
Cap and Bucky give chase (to the tune of old timey peye-ano playin'), and eventually corner the Toad in a room. But he hits the light switch, plunging the place into darkness! Then, in a scene familiar to anyone who's ever seen a Scooby Doo episode on television, when the lights come on, they've grabbed...
... NOT the Black Toad. It's Riggley, the owner of the Badgers team. Very unfortunate for Riggley, since he's figured out the Black Toad's identity and rather than announcing it, he announces that he's about to announce it.
As anyone who's ever seen a thriller or mystery movie on TV knows, announcing that you're about to announce who the killer is is the surest to get yourself killed. Sadly, this is 1941, and television hasn't been invented yet, so Riggley has no idea he's dooming himself.
Sure enough, he's blow-gunned down and falls dead faster than Angela Lansbury as Salome Audubon in Agatha Christie's Death on the Nile (1978).
But much more vocally.
The moral of this section? Watch more television, kids.
