said. He put a teacup carefully on the counter.
âI donât think he did, either, Benny,â agreed Jessie.
âItâs going to be a hard mystery to solve,â said Violet. âThe Elizabeth Star was in a room without windows and only one door. No one went in or out until we got there. And no one went in or out of the building except residents and their guests, according to the doorman.â
âBut someone did go into that locked room without setting off the alarm. And whoever it was took the diamond. Weâll have a lot of work to do, to figure this mystery out,â Henry said.
âWe will,â said Jessie confidently. âWeâll start first thing tomorrow morning.â
CHAPTER 5
A Taste for Diamonds
âM r. Leed,â said Jessie the next morning when the Aldens came downstairs after breakfast. âMay we ask you some questions?â
âDo you need directions to somewhere in the city?â asked Mr. Leed. He had a fresh newspaper spread out in front of him and was doing the crossword puzzle.
âNo. Weâre working on the mystery,â said Benny.
âMystery?â said Mr. Leed. âWhat mystery?â
âThat one,â said Henry, pointing at the headline of the newspaper. It said, TWINKLE, TWINKLE, ELIZABETH STAR, WE ALL WONDER WHERE YOU ARE .
âOh,â said Mr. Leed. âInteresting.â
âYes. It is. We were in Mr. Poundâs penthouse when the diamond was stolen,â said Benny.
âYou were?â Mr. Leed looked startled.
âNot exactly,â Jessie said quickly. âWe were there when Mr. Pound discovered it had been stolen. And we want to help him get it back. So we were wondering if we could look at your logbook. You know, the book where everyone who doesnât live here and isnât a guest has to sign in and out.â
For a long moment, Mr. Leed looked at them. Then he pushed the logbook toward them, flipped the pages back, and said, âHereâs the log from yesterday.â
âWe want to look at who signed in and signed out last night,â Jessie said. âBetween six-thirty and eight oâclock. Thatâs when the robbery happened.â
âGo ahead,â said Mr. Leed. âI donât know what you expect to find.â
âYou never know,â said Jessie. They bent over the logbook.
Running her finger down the page, Violet said, âSomeone delivered pizza to Apartment 6E at six-thirty and signed out at six-forty-five.â
Henry took a notebook out of his pocket and wrote it down. Jessie said, âAnd Lydia was here at six-forty-five. She took the dogs out for Apartment 3W at six-fifty. She came back at seven-twenty, but didnât sign out again until seven-fifty.â
âThatâs a long time,â said Violet as Henry wrote this down, too. âThirty minutes. Hmmm.â
âAnd then no one else,â said Jessie.
âSounds like a quiet night. Saunders was lucky,â said Mr. Leed.
The Aldens looked amazed. âA quiet night!â cried Benny. âBut the diamond got stolen.â
âOh,â said Mr. Leed. âRight.â
Henry had one more question. âIf you leave the desk, can anyone come in the door?â
âOf course not!â Now Mr. Leed looked indignant. âWe lock the door if we have to leave the front desk. And weâre never gone more than five minutes.â
âThank you,â said Jessie. She turned and led the way back to the elevator.
âWhere are we going?â Violet whispered as the elevator doors closed behind them.
âBenny and I are going to 6E to see if pizza really was delivered there last night. Because if it wasnât, maybe it was just a trick to get into the building to steal the diamond.â
âRight,â said Henry. âAnd Violet and I can go to 3W and see if Lydia walked the dogs last night â and why it took her so long to leave. She could have
