Detective Comics #35 - pt. 1

This installment of The Batman infamously opens on Batman standing in a doorway with a smoking gun in his hands -- it has nothing to do with the story, but must have impressed Kane as being a really cool opening panel.

This is, I think, the only story that makes out Bruce to be an amateur writer.

The story is a confusing jumble of racism, as the Batman tangles with Indian natives, working for a Chinese Fu Manchu-like character, who is actually a white man in disguise.

The Batman pauses to announce his presence before springing on two robbers, making me think his initial signature move was making sure bad guys got a good look at his costume before attacking them (and it makes me wonder if I should have rules on changing signature moves over time).

The "Batmobile" (not yet called that) is still only a high-powered roadster the Batman happens to drive.

Sin Fang's henchmen use khopeshes (swords; at least they aren't hatchets). Sin lures the Batman into a trapped room where the door slams shut and it slowly fills with mustard gas. Anticipating the 1960's Batman, the Batman just happens to have an anti-mustard gas pellet in his utility belt (marking the first time something weirdly random is drawn from the utility belt). Utility belts have been a trophy item since Book II: Mobsters & Trophies.

Despite the fact that Sin has lured the Batman into a mobster encounter and a trap already, the Batman still falls into another trap -- this time, a pit trap that is filled with water at the bottom, but there's a pipe in the wall partway down that he can grab at.

The Batman seems unconcerned when he knocks "Sin Fang" out a window to plunge to his death.

Fictional names for foreign countries often change from issue to issue, but this is the second issue in a series of Spy stories where Germany is "Luxor."  Being a spy is easy when you see the ambassador walking down the street and then just have to look through a door transom and you spot him colluding with a submarine commander in person.

Bart Regan uses a "sensitive microphone" to listen to a conversation through a brick wall. He wears a bulletproof vest in his installment.

Tangling with the commander, Bart is grappled, thrown prone, shot at, and knocked out with a blow to his head. The shot narrowly missed his ear -- though combat in Hideouts & Hoodlums is abstract enough that it could have been a "hit" and still caused hit point loss, without causing any physical wound.

Commanders are 7th-level fighters, so Bart is hard-pressed every time they fight. Bart is twice saved by convenient encounters -- the first time by a passing beat cop, and the second time by a rival spy who takes Bart out of the scenario and finishes it himself (poor refereeing!).

Buck Marshall, Range Detective starts off with an unusual premise, making it the best start to a Buck Marshall story yet -- Buck robs a stagecoach! It turns out, Buck is robbing it because he knows robbers are on their way that are too numerous for him to stop (6 to 1 odds), so he appears to rob the coach and tricks the robbers into chasing off after him. Finding their lair, Buck puts aniline powder in all the gloves he finds, so the dye will make their hands and they can be found later. Aniline powder is a real thing.

One of the robbers calls Buck a "gink" -- this is old slang that only means "guy." 

Next up is Steve Malone, District Attorney. This story establishes that Steve is based out of New York, and that his secretary's name is Nancy. Steve has three assistants who serve as supporting cast in this story, but none of them are named.

Ethnic restaurants are not treated with much respect circa 1940; an Italian restaurant is called a "spagetti house" (not my misspelling).

The hideout of the kidnappers Steve is after is only accessible by a bridge. The kidnappers watch the bridge and plan to shoot anyone crossing it, but Steve foils them by swinging hand-or-hand underneath the bridge (basic skill check?)
