I remember quite clearly, walking over here with you after that long dinner we had together, and then seeing poor Eggy's feet through the door. "Do you know what? I don't think I did anything. "I've never been here before, I didn't even know where he kept the stuff. "Don't you remember our sitting there after you called the police, and Arnold passing out the glasses?" "That was Arnold who got out the Scotch," said Betsy. "The only things you opened were the door to the liquor cabinet and a bottle of Scotch, Betsy." Charles laughed at her. "I was dizzy from the fumes, and I knew I needed to do something fast." Very good move, too, I thought at the time." All I could think of was that maybe he was alive and we could still save him." "For my part, I'm sorry about pulling him out of the oven - tampering with the evidence and all that," said Arnold. "The lights were already on, Arnold," Charles replied. Didn't it occur to you that a spark at the light switch could have blown us all up." "That was a pretty dangerous thing you did, Charles," said Arnold, "turning on the lights the way you did. When you finally got the door opened, the gas just streamed out." You seemed to take forever getting your key out. "There was gas in the hall, all right," said Charles. We'd still be in the hall if Eggy hadn't given me a key last week." The place was locked up, and sealed too, tighter than a drum. "There is no way that you could have smelled the gas before we opened the door. "Don't dramatize yourself," said Daisy coolly. My heart turned over, I thought to myself, he's dead. We rang the doorbell, and no one came and no one came, and then I smelled the gas. "The thing I remember is the gas in the hall. "I have no idea what he said or what time we got here," declared Betsy. "I said it was just seven on the nose," said Arnold. "Arnold said that it was six o'clock at the time, just before we opened the door. "But we all arrived at seven," Charles pointed out.
We were all together having dinner for at least two hours before we came over here." "If, as the police say, Egmont was injured between four and five," said Daisy, "that must let us all out.
Before they can be separated, the four young people who found the body - Arnold, Betsy, Charles and Daisy - eagerly begin to tell their story. From the beginning, it is pretty clear to the police that this was no accident. Knowing this much can you figure out who is the guilty one?Įgmont VanDorn has been found dead in his apartment. But, the killer wanted to confuse our trail - and so coolly lied from beginning to end." "The way I reconstruct the crime, the innocent people were so excited when they first talked to us, they each got one fact wrong. "Interesting puzzle, the VanDorn case," Sergeant McGuffy remarked to his lieutenant one day after it was all over.
