The concluding half of the Spook’s introduction is featured in Detective 435 (June/July 1973), by Frank Robbins, Irv Novick and Dick Giordano, who also did the cover.
Batman’s attempt to draw out the Spook fails, and he realizes that the Spook must have multiple bugs on the hoods he ensures, and was getting a duplicate signal, clueing him in that the Big Turk in prison was a phony. And Batman is dead on with all of that.
He then, finally checks out the scene where the Batmobile was stolen, and figures out how that was done – a huge trick that relied on Batman driving onto one exact street – although the Spook more or less implies that there are similar set-ups around Gotham. So he must employ a road works crew.
So Batman follows the tunnel and confronts the Spook, but finds it all but impossible to actually tale hold of the man, between his tricks and flexibility. He finally plays on his ego and goads him into a position where Batman can grab his controls and neutralize them.
The story has a surprising twist at the end, as it’s revealed that the Spook is Val Kaliban, a man executed 10 years earlier.
The Spook returns in a couple of months in the pages of Batman.
Jason Bard has his final outing in Detective done by Frank Robbins. It’s better than his Don Heck stories, but it bothers me in a different way. Jason is on hand when a man dies while group parachuting, by being stabbed in the back. As can be seen in that very first page, they all go down together as a unit.
When the man hits the ground, he has a knife in his back. Jason ponders which of the other skydivers could have done this. And has so much trouble figuring t out he goes up in a plane with them to re-enact it.
Only then does he realize that the killer had to be the one standing behind the dead man when they jumped. The only possible person. AND, Jason, with his bad leg, is going to sky dive? REALLY? Because he wants to be even more crippled?
So that’s the end of Jason Bard’s less than impressive run in Detective. He would remain a supporting character and pop up all over the Batman books as the years pass. He would even get a back-up series again in Detective, part of One Year Later.
