Chapter 1:
Jackie and the others have arrived in New York. "Why are we here again," asks DogDay.
"Uncle made deal with antique seller in this town," says Uncle.
...
They arrived, but no one's in. Uncle finds a note. "Busy at work," Uncle reads, "what could this other job be?"
...
"Listen to this Baxter..." says April O'Neal, "...It says that the police were battled by these bank heists... They can't figure out how the vaults were tunneled into so swiftly and neatly, through concrete and steel! The tunnels were so narrow only a child could have crawled through them!"
"...Or a very small adult. April, why are you boring me with this?"
"Well, it's just that I've been thinking..."
"Yes?"
"The Mouser unit... They could have dug tunnels like that, easily..."
"Oh, come now April... Why would the Mousers dig holes in bank vaults? You helped program them, remember?"
"But what if someone else has gotten control of a couple Mousers, and reprogramed them?"
"Really April... The mother computer would know if that happened and would tell me!"
"I... I suppose you're right, Baxter... still, I..."
"April, I assure you that no one else has control over the Mousers except you and I. Come on... I have something to show you."
