All Aboard!
At Duncan's Cove, above a secret submarine base, The Green Hornet and Kato encounter Nazi agents. The enemy operatives fight fiercely, and covertly. Until The Hornet and one spy tumble down the ravine. Below more Nazis are setting explosive, while frogmen steal their way to blow up the subs.
While the navy base is lost, the subs make it to open water.
Sprecht and his men momentarily capture The Hornet and Kato. Until Yankee Commando arrives on the scene. The Commando is the new identity of Alpha Two. Still testing his strength, he eliminates Sprecht. The Hornet and Kato make it back to the city with clues from the saboteurs vehicles.
Later, Britt Reid confers with Commissioner Higgins and Major Case. The Commissioner's secretary, Dorothy, gives them the final puzzle piece they need.
The Hornet boards a certain DC Flyer train. He is nearly spotted by a couple of reporters for another major metropolitan newspaper. The reporters are onboard to interview President Franklin Delano Roosevelt. The Hornet reveals his true identity to the President, only to find that he's been replaced with a Nazi look-alike! Who calls on an Army captain to shoot him as a Nazi assassin!
The Good
Ron Fortier and Jeff Butler's story starts to pick up steam, racing headlong toward the ultimate conclusion. Once again, The Hornet and Kato face a death trap. This time they are able to fight their way free. However, staring down Sprecht's guns, they can't escape on their own without intervention from another character, The Commando.
Nice mention of the Namor, the Sub-Mariner. Also, a nice cameo by Lois Lane and Clark Kent.
The Bad
Just a couple quibbles. Cool appearance by Yankee Commando, one of many homages to Captain America. Commander Steel, The Shield, and now the Commando. Unfortunately, when the Commando intervenes, he's the one who takes out Sprecht, not The Hornet. Which is a shame. This is The Hornet's book. He's in action, but not really fully shining in his own book.
This may or may not be a bad thing, but the Commissioner's secretary provides the vital piece of information, from reading The Daily Sentinel! It's that "What a fool I've been!" moment where Britt Reid admits he's disconnected. A reader might see that and scream "Ixnay! Ixnay on the identity-ay!"
The Skinny
This is still a riveting adventure, quibbles aside. The Hornet and Kato take out the enemy and move from one clue to another.
Sting of The Green Hornet 3, "The Terror Express" earns four stars for packing in actions - and more cameos.
