“I think it was LSD,” said Toni suddenly. “I’ve been thinking about it. It’s a hallucinogen.”

“And how come you know about it, young lady?” demanded Wilkes.

“It was a case we turned over to Worcester CID earlier this year,” said Toni. “Do you remember, Agatha? A mother thought her son was on drugs. I followed him to that club in Evesham and found they were giving out tabs quite openly. So I informed the police and the club was raided.”

“What are tabs?”

“LSD is usually found on little squares of blotting paper called tabs,” said Toni. “It’s also a clear liquid. All someone had to do was tip a few drops into each of the jam-testing dishes. I gather the show was set up early in the morning and then the organizers went home for breakfast. It might be an idea to trace the source of the drug. LSD isn’t all that common in the clubs these days. It’s all Ecstasy or crack cocaine or heroin.”

Toni was a pretty young girl aged eighteen. She had naturally fair hair. Collins threw her a look of dislike. “You seem to know a lot about drugs.”

“It’s my job,” said Toni. “I’m a detective. You see, that’s how I found out our two organizers had left the tent empty. Before the tent was opened to the public, the various jam dishes were covered with white cloths fastened with drawing pins. The tent was only opened to the public after Betsy had finished singing.”

“It wasn’t us,” wailed Mrs. Glarely.

“We’ll need the names of all the women who contributed jam,” said Wilkes. He sighed. “Are there many?”

“Only six,” said Toni, pulling out a notebook. “I have their names and addresses here.”

“Good girl,” said Wilkes, and Agatha felt a little stab of jealousy. She felt tired and jaded, and there was Toni looking as fresh as a daisy. Had George noticed Toni? That was the trouble with middle-aged men. They were allowed to fancy young girls. Middle-aged women fancying young men were called cradle snatchers.
