LIKEWISE with the being ticked off about that little "detective chatroom" cop out in 845 (though I suppose Batman was employing the same technique, which belittles his deductive abilities as well). Especially considering how Riddler essentially solved the Atkins homicide in 828 all on his lonesome, with Batman hot on his heels. It was rather disconcerting of Dini to contradict himself in such a manner.
However, I find that other writers are giving Riddler credit for his analytical and deductive brilliance; there was a snippet in Outsiders (the issue number escapes me), and Cass believed Eddie to be a suitable replacement for Batman's detective aspect. Trinity 12 was already mentioned here, and even in Gotham Underground Eddie was able to detect Nightwing's identity under his Matches Malone-wannabe disguise right off the bat.
It's disappointing, though, that Dini of all people seems to be dropping the ball. Why build Riddler up to be an intellectual equal to Batman, only to kick him around later? I absolutely love the detective angle Eddie has going for him, but I'd like to see it used successfully more.
