tunnel,â Soo Lee said when they didnât see signs of anyone in the back hall.
âOkay, okay,â Jessie said. âLetâs check.â She turned the doorknob to the passageway door, but it was locked. âI guess you have to have the key like Pete did. Letâs just wait for Benny and Henry to come back.â
Across the street, back in the museum, Henry and Benny banged on the side entrance door. Again, they heard a voice: âThe museum is closed! Come back tomorrow.â
They banged again, and this time Pete and Nosey came running.
âOh, itâs you and Benny,â Pete said. âSorry it took so long, but Nosey thought he heard something down at the other end of the museum.â
âHe did?â Benny said. âWell, guess what? We saw somebody go down the manhole in the street. We came to find out if the person came into the museum through the underground part.â
Pete laughed. âWell, if somebody did, the person is stuck down there. You have to have a key for any of the doors that lead off of it. And if you had a key, then you sure wouldnât need to go down the manhole to get inside the museum or apartment. You could just walk in the front door!â
This didnât stop Benny. He was ready for an adventure, and he was going to have one. âWhat if somebody wants to sneak in a secret way? Maybe Nosey did hear somebody.â
Pete patted Bennyâs curly head. âTell you what, Benny, Iâll take you down to the passageway myself, and weâll check it out. Thatâs my job. First let me take a look at the television screens to make sure everything is A-OK in the rest of the museum.â
Benny and Henry walked quickly to the guard booth. This time Pete let Benny inside so he could get a look at the screens that showed different rooms in the museum.
âSee any prowlers or anything suspicious on any of those televisions?â Pete asked Benny.
âJust me!â Benny said with a laugh. He made faces at the camera that was pointing right at him from the ceiling of the guard booth.
âThatâs a dangerous face if I ever saw one!â Pete joked.
Henry checked out the row of televisions, too. âThis is pretty neat,â he said. âDo you ever see anything on the screens?â
âNot so far,â Pete said. âItâs pretty dull. Once in a while I get excited when I see a person on the screen, but it always turns out to be somebody who works here. I still like walking around, not just watching these televisions the whole night.â
âHey, why is this screen dark?â Henry asked.
Pete explained, âOh, that oneâs been on the blink for the past couple of weeks. Itâs the screen for Dino World. We canât seem to get the camera working right. Not that it matters. Titus Pettibone is a better guard of that place than any of the real guards.â
âBut who watches over the place now that heâs away? Donât forget, last night it was unlocked,â Henry said.
Pete looked away. âOh, uh, well ⦠maybe one of the work crew got tired of asking Titus for the key and taped the latch to go in and out. Thereâs a lot of work in there that still needs doing before opening day.â
Benny was getting impatient. âIs there a television screen for the passageway? If we donât get down there, the person I saw will be gone.â
âThe passageway isnât rigged up to the remote cameras,â Pete said. âOnly Mr. and Mrs. Diggs and a few other museum people ever use it. Or utility people when they check the water and gas lines. Anyway, the doors down there and the service elevator all lock from both sides.â
Just as Pete had said, the passageway was deserted when they got there.
âRats! We took too long,â Benny said. âThe person got away.â
âGuess so, Benny,â Pete said. âWant to help me out on my post tonight? Maybe
