taken the diamond then.â
âWeâll meet out front in twenty minutes,â said Jessie as the elevator doors opened on the third floor.
âOkay,â said Henry.
Henry and Violet walked to 3W and knocked on the door. A moment later, they heard small bodies thumping against the door and the muffled sound of barking. But no one answered.
Henry knocked again, harder. The barking grew louder. But still no one answered.
âI guess whoever lives there has gone to work,â said Henry. âWeâll have to come back later to ask about Lydia.â
Meanwhile, Jessie and Benny had found someone home in Apartment 6E. A sleepy-looking man with shaving cream on half his face opened the door. He yawned when he saw them and said, âWhat is this? Halloween trick or treat?â
âNo,â said Jessie. âWeâre visiting Mrs. Teague on the ninth floor.â
âCongratulations,â said the man. He yawned again and started to close the door.
âWait,â said Benny. âWe want to ask you a question.â
âAh,â said the man. âTrick or question . Okay, ask your question.â
âDid you order pizza last night?â
âI did. Everything, hold-the-anchovies. My usual from the corner pizza. Why?â Now he didnât look quite so sleepy.
Jessie explained about the missing diamond. âWeâre trying to help Mr. Pound find out who took it,â she said. âAnd we wanted to make sure that someone really delivered pizza to your apartment.â
âHe sure did. Leo. Heâs been delivering pizza to me for a few years now. Paying his way through college. He had to wait while I found money to pay for it. Thatâs why it took him so long,â the man said.
âThank you,â Jessie said.
âYouâre welcome,â the man said, and closed the door.
Downstairs, Jessie and Benny found Henry and Violet sitting on the low wall around one of the flower beds outside the building.
âThe pizza man didnât do it,â said Benny. âHeâs a real pizza man, not a diamond thief.â
âNo one was home where the French bulldogs live,â reported Henry. âSo we couldnât find out if Lydââ
âShhh,â said Jessie. She waved. âHi, Lydia,â she said.
They all looked up and saw Lydia striding down the sidewalk.
âGood morning,â said Lydia. âCanât stop to talk. The dogs are waiting.â She hurried by.
When she passed, Henry said, âI know what we should do. Letâs follow Lydia after she walks the dogs. Maybe she will act suspicious.â
âLetâs go across the street to the park,â suggested Violet. âWe can watch for Lydia there and she wonât see us.â
So that is what they did. They waited until Lydia had returned from walking the five French bulldogs. Then they followed her as she left Mrs. Teagueâs building.
The Aldens trailed after Lydia as she strolled along the park. At the bottom of the park she turned left. She walked across to Fifth Avenue and turned right, heading downtown. A few blocks later she stopped to stare into a window.
âTiffanyâs,â said Jessie. âItâs a very famous jewelry store.â
Sure enough, even from where they stood, hiding behind a mailbox and lamppost, the Aldens could see lots and lots of diamonds and pearls and all kinds of precious jewels on display in the windows of the store.
âMaybe she is going to try to sell the diamond to them,â said Violet.
But Henry shook his head. âNo. A famous store like Tiffanyâs would never buy a stolen diamond. Lydia would have to sell it secretly to someone dishonest.â
âMaybe she wants to buy fancy jewelry when she sells the diamond and she is just window-shopping now,â Jessie said. âSomething even nicer than her crystal necklace.â
âOr maybe sheâs just trying to figure out
