molds. Isadore still has his moon, of course. Pierre’s sun is safely sealed in Demerara’s flat. But Marcel’s star isn’t nearly so well protected. We need to find it and get it to a much safer place—in a special government vault—because it’s better to keep the molds in different places. We need your magical powers to find it.”
“I never knew we had magical powers; does it mean we can do spells?” Lily asked.
“Yes, in theory,” J said. “But you don’t need to do anything complicated now; you just have to be there.” He broke off to sigh, “I must be honest; this could be dangerous, and it was quite a problem getting clearance.”
“There’s no other way.” Demerara was firm. “The immortality chocolate can’t be made without all three of them—and Marcel’s mold has been lost since 1938. My personal opinion is that he had it with him when he died in the accident.”
“That means it must be at the bottom of the river,” Oz said. “Why do you need us to find it? Couldn’t you just send down some divers?”
“We’ve tried all the ordinary methods.”
“But—hang on—” Oz was trying to get the complicated story straight. “All three brothers were on the tram—right? So why didn’t Isadore just grab the mold from Marcel while he was drowning?”
“That’s a very good question,” J said. “And the truth is, we don’t quite know. It’s possible that the mold had some sort of inbuilt resistance to wickedness. We do know that Isadore has searched the riverbed at least twenty times since 1938, but he never found a thing. This department—which, of course, doesn’t exist—has been assigned a special unit of river police. They will contact you.”
“What should we tell our parents? Are they included in the Official Secrets Act?” Oz asked.
“Ah.” J was a little uncomfortable. “Thank you for reminding me; it’s rather important. I’m sorry, but your parents must know absolutely nothing about this. We’ll provide you with excellent cover stories.”
“I don’t think I’m that good at lying,” Caydon said. “My gran can see through walls.”
“That won’t be a problem. We’ve taken certain steps to stop your parents from noticing anything. They won’t be asking any awkward questions.”
“Are you sure?” Caydon was doubtful.
J and B62 exchanged smiles. “Not even your gran, I guarantee it.” He stood up. “Thank you all very much—and jolly good luck.”
He shook hands with them, and shook Demerara’s paw. A few minutes later the three children and their pet carrier were being escorted out of the building.
“Incredible,” said Oz. “We’re secret agents! What do we do now?”
Caydon glanced at his watch. “This secret agent had better get home—before his gran finds out he hasn’t picked up the dry cleaning.”

Secret Agents
The government agency that did not exist was very efficient. Next morning, Dad said, “Why didn’t you two tell me you’d signed up for this diving course?”
“Diving? What’re you talking about?” Lily began. Oz nudged her. “We—we forgot.”
Dad was reading an official-looking letter. “Well, it’s a very good course, run by the river police. They’re sending someone to pick you both up this afternoon.”
“It sounds a bit dangerous,” said Mum.
“I think it’s great,” Dad said firmly. “What with moving houses and the new baby coming, Oz and Lily aren’t having much of a summer holiday this year—they deserve a bit of fun.”
“But Lily,” Mum said, “you won’t like diving; you don’t even like swimming.”
Lily tried to look casual, though her stomach was going up and down like a lift. “I’ve changed my mind.”
“Well, if you’re sure—Bruce, do they need any special clothes?”
“Just ordinary luggage for one night away,” Dad said, looking at the letter. “Everything else is provided.”
“I’m terrified,” Lily admitted to Demerara, when the two of them were
