Batman Issue 104

The Man Who Knew Batman's Secret!
Batman and Robin nab a pair of John Varden's hoods using a bazooka to loot a bank. The captured criminals refuse to rat on their elusive boss, but let slip the fact that Varden plans a big operation soon. To trap the gang leader, Batman and Robin hatch a plan. The next day, Batman and Robin patrol the rooftops of Gotham City in plain sight, draw a crowd of reporters, and attract another comical figure who claims to be Thaddeus Crane, a detective from upstate who has come to study Batman's and Robin's crimefighting methods. Crane climbs to a roof top to interview the dynamic duo, and catches Batman with his cowl off, in the process of changing to Bruce Wayne. Thaddeus Crane announces to the reporters that he knows Batman's secret identity, and Batman and Robin admit they will have to guard him to keep it secret. Crane is hired by the chairman of a camera show featuring a huge camera as an exhibit and a movie company president to guard the exhibits and his bejeweled star Laura Lee, respectively. Though Varden's mob strikes in both places, Batman and Robin thwart their efforts and make it seem as if Thaddeus Crane has overcome the crooks. John Varden's mob eventually cons Crane into their clutches, and he meets with the mobster, though he steadfastly refuses to reveal Batman's identity. But Batman and Robin, who have used Crane (with his permission) as bait for their trap, break in and defeat Varden and his gang. Crane later announces he is leaving Gotham, and disappears forever. But, in the Batcave, he unmasks before Batman and Robin as their butler, Alfred Thaddeus Crane Pennyworth.

Robin's 50 Batman Partners!
Batman breaks his ankle during a fracas with the Sparkles Grady mob, and Robin has to take his place as representative at the Batman Exposition. The Exposition, covered on TV, features fifty images of Batman in various forms--as a colossal robot, a giant statue, a mechanical figure on a great clock, and so forth. Grady, watching the program, notes that Robin still holds the pouch of diamonds recovered from their heist, and takes himself and his gang to the exposition after hours where only they and Robin, who is taking photographs of the exhibits, are present. Robin is outnumbered, and endangered when the gang chief orders the Batman-robot to "get" him, but uses the many Batman exhibits (including the mechanical clock figure, who smashes the robot with a stroke of his hammer) to even the odds. Finally, exhausted, Robin tries out a mystery exhibit. It proves to be a giant fireworks display forming a great head of Batman, and its brilliance momentarily blinds the thugs. He nets Grady and his gang with the cape from the giant Batman statue and summons the police to haul them away. Later, at Wayne Manor, Bruce expresses regret that he could not have helped Robin, but Robin replies that he was with him all the time.

The Creature from 20,000 Fathoms!
Batman and Robin, as honorary members of the 50 Fathoms Club, a group of underwater specialists, attend a meeting at which deep-sea diver Devoe presents photos of Babonga, a giant saurian monster which appears periodically at a Pacific island which Devoe visited. The members vote unanimously to put up the money to bring Babonga and exhibit it, with all of them together (including Batman and Robin) in on the Babgonga shows up as promised and the club members take aim with rifles loaded with mercy bullets--except that a first shot goes awry and blasts a section of ship's rail out, explosively. Batman, realizing their bullets have been switched, has the hunting party hold their fire and repels the beast with a brilliant flash from a camera. One of the party, he says, wishes to kill Babonga rather than bring it back alive. Batman foils an attempt upon on his own life and lures Babonga out of danger when senses their gas bombs have been filled with poisonous acid instead, but the culprit remains beyond his grasp. Then when the dynamic duo go down in a bathysphere, their connecting chain to the ship is cut--as they had expected. The pair go out in diving suites they had left in the bathysphere and beard Bobanga in its lair, drugging it with paralyzer serum. The two heroes surface with the evidence to condemn the guilty party--Babonga's egg. Devoe, the malefactor, confesses that he had intended to kill Bobanga so that the egg which he owned would the only living member of its species, thus enabling him to make a fortune himself from the exhibitions. Batman replies that he knew his identity after the assault, since the deep grooves on his wrists, caused by his diving suit's sleeves, were a dead giveaway. Bobanga is taken back alive for exhibition and study. Batman remarks later that the egg will take a century to hatch, anyway, and when it does, it will hatch in the trophy room of the Batcave.
