"He didn't wear it at the funeral," said Margaret. "I looked most carefully when he knelt down to pray."

"Do you think he knows what that key unlocks?" said Hugo.

"He may well do," Margaret replied, "but that doesn't mean he knows where to look for it."

"Father should have told us where he had hidden his collection in the first place."

"You and your father were hardly on speaking terms towards the end," Margaret reminded him. "And he considered Angus to be weak, and far too fond of the bottle."

"True, but that doesn't solve the problem of the key."

"Perhaps the time has come for us to resort to more robust tactics."

"What do you have in mind, old gal?"

"I think the vulgar expression is 'putting a tail on him'. Once Nick is released, we can have him followed. If he does know where the collection is, he'll lead us straight to it."

"But I wouldn't know how to..." said Hugo.

"Don't even think about it," said Margaret. "Leave it all to me."

"Whatever you say, old gal," said Hugo as he attacked his second egg.

CHAPTER THIRTY-SEVEN

DANNY LAY AWAKE on the lower bunk and thought about everything that had taken place since Nick's death. He couldn't sleep, despite the fact that Big Al wasn't snoring. He knew his last night at Belmarsh would be as long as the first-another night he would never forget.

During the past twenty-four hours, several officers and inmates had dropped in to say goodbye and to wish him luck, confirming just how popular and respected Nick had been.

The reason Big Al wasn't snoring was that he'd been shipped out of Belmarsh the previous morning and transferred to Wayland prison in Norfolk, while Danny had been revising for his A levels in Nick's name. Danny still had the maths papers to look forward to, but was disappointed to have to forgo the English exams as Nick was not taking them. By the time Danny returned to his cell that afternoon, there was no sign of Big Al. It was almost as if he had never existed. Danny hadn't even been given the chance to say goodbye.

By now Big Al would have worked out why Danny had been to see the governor, and he'd be fuming. But Danny knew that he'd calm down once he settled into his C cat, with a television in every cell, food that was almost edible, an opportunity to visit a gym that wasn't overcrowded and, most important of all, being allowed out of his cell fourteen hours a day. Leach had also disappeared, but no one knew where, and few cared enough to ask a second time.

During the past few weeks Danny had begun to form a plan in his mind, but in his mind it had remained, because he couldn't risk committing anything to paper. If he was discovered, it would condemn him to another twenty years in hell. He slept.

He woke. His first thought was of Bernie, who had been robbed of his life by Craig and the misnamed Musketeers. His second was of Nick, who had made it possible for him to be given another chance. His final thoughts were of Beth, when he was reminded once again that the decision had made it impossible for him ever to see her again.

He began to think about tomorrow. Once he'd had his meeting with Fraser Munro and tried to sort out Nick's immediate problems in Scotland, he would return to London and put into motion the plans he'd been working on for the past six weeks. He'd become realistic about the chances of clearing his name, but that wouldn't stop him seeking justice of a different kind-what the Bible called retribution, and what Edmond Dantes described less subtly as revenge. Whatever. He slept.

He woke. He would stalk his prey like an animal, observing them at a distance while they relaxed in their natural habitat: Spencer Craig in the courtroom, Gerald Payne in his Mayfair offices, and Lawrence Davenport on stage. Toby Mortimer, the last of the four Musketeers, had suffered a death even more dreadful than any he could have devised. But first Danny must travel to Scotland, meet up with Fraser Munro and find out if he could pass his initiation test. If he fell at the first hurdle, he would be back in Belmarsh by the end of the week. He slept.

He woke. The early morning sun was producing a feeble square of light on his cell floor, but it could not disguise the fact that he was in prison, for the bars were clearly reflected on the cold gray stones. A lark attempted a cheerful tune to greet the dawn, but quickly flew away.

Danny pulled aside the green nylon sheet and placed his bare feet on the ground. He walked across to the tiny steel washbasin, filled it with luke-warm water and shaved carefully. Then, with the assistance of a sliver of soap, he washed, wondering how long the smell of prison would remain in the pores of his skin.

He studied himself in the small steel mirror above the basin. The bits he could see appeared to be clean. He put on his prison clothes for the last time: a pair of boxer shorts, a blue and white striped shirt, jeans, gray socks and Nick's trainers. He sat on the end of the bed and waited for Pascoe to appear, jangling keys and with his usual morning greeting, "Let's be having you, lad. It's time to go to work." Not today. He waited.

When the key eventually turned in the lock and the door opened, Pascoe had a broad grin on his face. "Morning, Moncrieff," he said. "Look lively, and follow me. It's time for you to pick up your personal belongings from the stores, be on your way and leave us all in peace."

As they walked down the corridor at a prison pace, Pascoe ventured, "The weather's on the turn. You should have a nice day for it," as if Danny was off on a day trip to the seaside.

"How do I get from here to King's Cross?" Danny asked. Something Nick wouldn't have known.

"Take the train from Plumstead station to Cannon Street, then the tube to King's Cross," said Pascoe as they reached the storeroom. He banged on the double doors, and a moment later they were pulled open by the stores manager.

"Morning, Moncrieff," said Webster. "You must have been looking forward to today for the past four years." Danny didn't comment. "I've got everything ready for you," continued Webster, taking two full plastic bags from the shelf behind him and placing them on the counter. He then disappeared into the back, returning a moment later with a large leather suitcase that was covered in dust and bore the initials N.A.M. in black. "Nice piece of kit, that," he said. "What does the A stand for?"

Danny couldn't remember if it was Angus, after Nick's father, or Alexander, after his grandfather.

"Get on with it, Moncrieff," said Pascoe. "I don't have all day to stand around chatting."

Danny tried manfully to pick up both the plastic bags in one hand and the large leather suitcase with the other, but found that he had to stop and change hands every few paces.

"I'd like to help you, Moncrieff," whispered Pascoe, "but if I did, I'd never hear the end of it."

Eventually they ended up back outside Danny's cell. Pascoe unlocked the door. "I'll return in about an hour to fetch you. I have to get some of the lads off to the Old Bailey before we can think about releasing you." The cell door slammed in Danny's face for the last time.

Danny took his time. He opened the suitcase and placed it on Big Al's bed. He wondered who would sleep in his bunk tonight; someone who would be appearing at the Old Bailey later that morning, hoping the jury would find him not guilty. He emptied the contents of the plastic bags onto the bed, feeling like a robber surveying his swag: two suits, three shirts, what the diary described as a pair of cavalry twills, along with a couple of pairs of brogues, one black, one brown. Danny selected the dark suit he'd worn at his own funeral, a cream shirt, a striped tie and a pair of smart black shoes that even after four years didn't require a polish.
