“Money,” said Hugh. “If you haven’t got enough money to buy anything you may want, or to pay for railway journeys, or to bribe people with, you’re done. I’ve got £1 5s. saved up in my money-box. I’ll take that.”

“I’ve got a sovereign my godfather sent me last week—a late birthday present, because he was at the front when my birthday was on.”

“Good,” said Hugh. “Then, food. You must have food with you, because you can’t be sure of being able to buy it, and you can’t carry on if you’re starving.”

“Cook,” said David, “has been crying ever since she found Danny was lost. If she hears we are going to seek for him she’ll give us any amount of grub.”

“Rope,” said Hugh. “We might have to let ourselves down into a pit, or out of a window.”

“Yes,” said David, writing in his book, “and the pit might be dark, so we might need two electric lights, and some candles and matches.”

“We might have to file some bars,” said Hugh. “Put down a file.”

“We might have to have a fight,” said David, “so I think we’ll take two of the old daggers out of grandfather’s armoury. We shall have to sharpen them, ’cos they’re awfully blunt.”

His eyes gleamed fiercely.

Hugh nodded. “But after the fight we might want to do first aid, so I think we must have bandages and lint and things.”
