Across town, at the Gotham Art Gallery…

"Are you sure this is the place? It doesn't look like anyone is breaking in."

"Looks can be deceiving, Robin. But my Bat instincts are telling me something is not right."

On the steps of the gallery, right in front of the door, is a green parcel tied in a purple bow. This has Riddler written all over it. Carefully, the dynamic duo approach and pry open the lid.

"Careful Batman, it could be rigged."

"It's just a card with a question mark on the back," Batman declares. "And a message on the front."

The note reads:

Riddle me this.

What suit would you have to be mad to wear?

"A straightjacket, of course," Batman deduces. "But what does that have to do with the statue?"

Upon inspection, the World's Greatest Detective can find no sign of forced entry but something's not sitting right. The Penguin is up to something, and so is the Riddler, but the Batman is in the dark. Perhaps the answers are within.

"We need to get inside."

"Holy switcheroo! That's breaking and entering."

"It's a necessary evil if we want to get to the bottom of this. My trusty Batkey will get us inside without setting off the alarms. Then we can investigate properly."

Sure enough, in just a few moments the lock springs open, and not a sound to be heard. It all looks empty inside. A security guard is quietly dozing at his station. Has the Penguin dosed him with gas or is he just sleeping on the job?

"Should we wake him up?"

"No, let him sleep. It'll give him time to dream up an excuse for his boss. He'll be in deep trouble if the statue is gone."

But, as they reach the exhibition room they realize the piece isn't gone at all. It's right where it's meant to be. Nothing else seems to be missing either.

"Could we have beaten him here?"

"I'm afraid not. Which can only mean one thing: the statue wasn't his target after all."

"That's right, Batman. Not so clever after all."

It's a familiar voice, arrogant and condescending. The Batman recognizes it instantly. The Riddler has arrived! The megalomaniac tips his bowler hat and flourishes his cane as he appears the other side of the podium on which the stork sits.

"How did you get in here?" Batman demands.

"When is a jar not a jar?"

"When it's a door."

Batman scowls and glances back. The door to the gallery through which they entered has been left ajar. While the Riddler laughs, Robin's face reddens. It was silly mistake to make.

"What do you want, Riddler?" Batman asks.

"The same as you: Penguin's plot thwarted. But the oversized fowl has you on a wild goose chase!"

"What do you know? Where is he?"

"I can't be seen to be helping so-called heroes. But I left you a clue outside. Better hurry if you want to catch him."

"Wait!"

"Sorry, Batman, I really must be going."

"I may have let you in, but I'm not letting you out that easy!" Robin yells.

As the birdarang flies from the young hero's hand, Riddler leaps into the air and presses a button on the side of his cane, releasing a screen of smoke. The birdarang misses and clatters off the wall, but the villain is gone.

"He stole your disappearing act."

"If only it was the only thing he stole. There's a painting missing."

"At least the statue is still here."

"Of course it is. Riddler couldn't carry a stone sculpture by himself. And neither could the Penguin. I should have seen it before."

"Then where is the Penguin?"

"The Riddler's assistance points us to Arkham Asylum. Why exactly he is assisting us is a riddle for another day."

"What if it's a trap?" Robin asked anxiously.

"That's a chance we'll just have to take."
