through the door at us. âWho did you say you were?â
âInvestigators,â said Boris.
âThen investigate!â
I tied Yetiâs leash around the lamppost and Stinky and I followed Boris into Mr. Hufflebergerâs office. Aside from the desk, everything was in its place. There was a lamp with a green shade and a coatrack with no coats. On the wall there was only one painting, and it wasnât by Picasso. The picture was of a moose. In the corner it said âHuffleberger.â
âYou paint?â Boris asked, as Mr. Huffleberger inspected the cat to make sure he hadnât been injured.
Mr. Huffleberger smiled a thin-lipped smile. âI used to,â he said. âBut I learned that my true calling is words.â
I wondered what my true calling was. I didnât think it was math, even if I did get problem No. 7 right. Art was still a possibility. And special-agent work, as long as we didnât mess up this case.
Boris pulled up an antenna on the side of his iPod and used it to measure the bites on Mr. Hufflebergerâs papers. He was about to measure the bite of Mr. Hufflebergerâs cat, too, but Picasso let out a vampire hiss.
âIâll estimate,â Boris said.
Mr. Huffleberger put his fingers on his neck, as if he was checking his pulse. âWho would do this to me?â he said. Something told me that a lot of people wanted to harm Mr. Huffleberger, including Ursula.
âAbout those photos . . .â I said, getting back to the original subject. A good special agent has to stay on task.
âIf we must,â he said. He put down the cat and opened the desk drawer to reveal a bunch of yellow folders. But under U, the only files he had were for âUmbrellas,â âUniversityâ and âUntitled.â The file for the artist named Ursula was missing.

Nanny X Reads Some Poetry
Nanny X changed from her bunny slippers to her regular shoes before we went into the White House. Then she led us past the people who were waiting in line for the one oâclock tour.
âMay I help you?â asked the guard.
âNanny X,â said Nanny X. âWeâre with NAP.â She waved her hands around to show that âweâ meant me, too.
I expected the man to send us back to the end of the line. I expected him to say âCome back later.â Instead he said, âWeâve been expecting you.â He spoke into his walkie-talkie: âItâs NAP.â
âIâll be right out,â a voice crackled back. A few minutes later someone came to meet us. She was not the president. She had short hair and wore a green dress and she walked almost as fast as Nanny X. She shined a blue light on Nanny Xâs badge. Then Nanny X pulled out IDs for me and Eliza and Howard. The woman looked at Howardâs ID and thenlifted back his bonnet so she could make sure his face matched his picture.
âLast week we had a visit from a sloth,â said the woman, whose name tag said Camila Lopez. âThis way.â She led us away from the tourists to a private metal detector and sent us through, one by one.
Beeeeeeeeep
. The fishhooks on Nanny Xâs hat set off the metal detector. Ms. Lopez put the hat on a conveyor belt with Elizaâs stroller and the diaper bag.
âNAP agent or not,â she said, lifting the diaper bag and the stroller off the belt again, âthese things stay here.â Nanny X got to keep her hat, though.
Ms. Lopez opened a heavy wooden door, and we followed her into the main building. âWelcome to the White House,â she said. âThe president receives an abundance of mail, all of which is sorted off-site. The letter from The Angler is still there for further inspection. But they released the statue and delivered it here this morning.â
We walked down a long corridor, past a bunch of fancy rooms that were named after colors and dead presidents. Then Ms. Lopez
