All-Flash #12

When District Attorney Clifford Devoe abruptly switches sides after losing a high-profile case to mobster Hunk Norvock, he vanishes from the public eye—only to resurface a decade later, drawn back into a web of crime and mystery tied to the Flash and a peculiar restaurant run by the Three Dimwits. The sudden call from Norvock reignites old alliances and unspoken threats, setting a tense stage where justice and loyalty are anything but clear.

In "Tumble Inn to Trouble! Chapter Two: The Thinker against the Doer!" from All-Flash #12 (1943), the reformed criminal Devoe—now calling himself "The Thinker"—turns his mind to orchestrating a string of high-stakes robberies, with the legendary "Sun" diamond as his next target. At the Tumble Inn, a bitter waiter’s revenge takes a bizarre turn when he slips Noddy a salad laced with Karma leaves, sending the man vanishing into thin air.

In "Tumble Inn to Trouible! Chapter Three: Hot Stuff, That Banana Oil," the Thinker’s latest scheme takes a turn when he sends his thugs to the Dimwit’s restaurant to steal the mysterious Karma leaves—supposedly the key to invisibility. But with the Scarlet Speedster already on the case, the real trick isn’t hiding in the leaves… it’s in how fast he can outmaneuver them.

In "Tumble Inn to Trouble! Chapter Four: Who's the Real Thinker?" from All-Flash #12 (1943), the Flash finds himself caught in a mind-bending trap when the Thinker manipulates his perception, making even the Fastest Man Alive doubt his own judgment. With the police convinced that the Three Dimwits are behind the crimes, the Flash must race against time to clear their names—before the real villain slips away.
