'Well, we'll see,' Aidan Bell told him.

Outside, a voice called, 'Hey, are you there, Rashid, and that Irish fuck with you?'

Bell and Rashid drew Brownings and approached the companionway.

Dillon had arrived fifteen minutes earlier, parked behind Billy and Harry, and joined them. He called Ferguson on his mobile.

'Where are you?' Ferguson asked, so Dillon told him. 'For God's sake. What are you playing at?'

'We still can't confirm the hit, the river or the Dorchester, so I'm taking the initiative. I'm with Billy and Harry. Bell left the Rashid house with Michael, they followed to Michael's boat at Wapping, and I've joined them.'

'Dillon, just listen to me.'

'No, I'm going to listen to me, General. I'll let you know how it goes.'

He switched off.

'He wasn't pleased?' Harry asked.

'Not really. He might be if we get a result.'

'How do we play it?' Billy asked.

Dillon took off his jacket and loosened his tie as he told them. He took but his Walther and slipped it into the waistband of his trousers at the rear.

'So you do the face-to-face, Billy, and you cover him, Harry.'

'Christ, Dillon, it's going to be cold in there.'

'Never mind that. Just watch yourself, Billy. Bell's tricky.'

'Don't worry about me. Think of yourself, Dillon. You're the one at the short end.'

'Fine. Just let me go in, then do your bit.'

Harry Salter crouched behind a bollard on the wharf. Dillon went down a ladder from the edge of the wharf and sank into the water. It was bitterly cold. He swam round to the other side of the Hazar and discovered, as he'd expected, a boarding ladder. It was then that Billy Salter approached the Hazar and called out.

'Hey, are you there, Rashid, and that Irish fuck with you?'

Bell said to Michael Rashid, 'You go to the stern, I'll take the bow, and don't screw around.'

Rashid said, 'I can hold my own.'

'Get on with it, then.'

Bell left him to go up the steps to the deck and Rashid went back through the cabins and pulled himself up the transom into the shadows of the stern.

Several things happened at the same time. Harry, behind the bollard, moved and Aidan Bell fired and hit Salter in the right shoulder. The force threw him back and Bell pulled himself over the edge of the wharf and scrambled away in the shadows.

Michael Rashid fired several times and Billy returned fire. Rashid moved back against the rail… and Dillon reached up and pulled on his ankles and Rashid toppled over. Dillon got an arm around the neck, took a deep breath and reached for the anchor line to pull himself under. Rashid struggled, kicking, and Dillon hung on until the struggling stopped. From the shadows, Bell watched, then faded away.

Dillon released the body and pulled himself up the ladder to the wharf. Harry was on his feet, groaning, Billy supporting him.

'Sorry, Dillon, we've lost Bell.'

'Michael Rashid is dead.' Dillon turned to Harry Salter. 'Get in the Shogun. You drive, Billy. Take us to Rosedene. I'll call Ferguson. He'll pull in Professor Henry Bellamy.'

'Dillon, I'm getting too old for this,' Harry said.

'Nonsense. We'll get Dora in to nurse you.'

As they drove away, he called Ferguson. 'You're going to need the disposal team. Yes, Michael Rashid, You'll find him in the water off Hangman's Wharf by his boat, the Hazar.'

'You did it yourself, I suppose.'

'Bell got away after shooting Harry in the shoulder. We're on our way to Rosedene. Get Bellamy. If he's not available, Hannah's dad. Only the best.'

'Consider it done, but Dillon, it would be nice if you talked to me sometimes.'

At Rosedene, Dillon waited with Billy. Bellamy was busy doing a bypass operation at Guy's, but Arnold Bernstein had been available.

Dillon said, 'Let's look in on Hannah.'

'Suits me,' Billy said.

She was sitting up, reading the Evening Standard, and looking far better than when Dillon had last seen her.

'So, the two musketeers. Bring me up to date.'

Which Dillon did.

Afterwards, she sat there brooding. Dillon said, 'What do you think?'

She was silent for a moment before she answered. 'Did anyone ever tell you the details of how Paul Rashid got his Military Cross in the Gulf War?'

'No, what about it?'

'Well, I've read the file. Villiers took twenty men behind the Iraqi lines in two Russian sand cruisers.

Rashid was in charge of group two. Ten men. But he made a mistake. He radioed Villiers on a clear line when it looked like there was an emergency, and the Iraqis picked it up, homed in and took out every man in his command.'

Billy said, 'Except Rashid?'

'Exactly. However, when Villiers got to where Rashid was, there was no one there. Just seven Iraqi soldiers, all dead and all emasculated.'

'And Rashid?' Dillon asked.

'Reached the Allied lines ten days later, walking on his own.'

Dillon said, 'Tony Villiers never mentioned this. Why not?'

Hannah smiled and shook her head. 'That's a comfort – even the great Sean Dillon can be naive. Look, Rashid is an Earl. And the product of Sandhurst, the Grenadier Guards and the SAS. Now, whatever else those outfits taught you, it wasn't how to cut off your opponent's cock. So that we keep quiet about.'

'This is all interesting stuff, Superintendent,' Billy said, 'but what's your conclusion?'

'He is mad. And he believes very much in revenge, in the harshest possible terms. Dillon has killed his two brothers, so Dillon must die.' She turned. 'It's the only certainty, Sean. He would be incapable of living with himself, with you alive.'

'And Kate?' Dillon asked.

'Empathetic inclusion. To aristocratic people, family is everything, and in this case there's a double dose, with the Dauncey on one hand and Rashid on the other. Kate is aware of her heritage and looks up to him as head of the family. It couldn't be otherwise.'

Billy said, 'So even she might want to kill Dillon off?'

'I would say so.' Suddenly, she looked tired. 'I need to rest.'

The door opened and her father looked in, still wearing his operating gown. 'They told me you were here.'

Billy said, 'How is he?'

'Well, my recommendation is that at your uncle's age, he should try not to get shot. Having said that, he's not going to die on us.' He moved to his daughter. 'How are you?'

'Tired.'

'Then go to sleep.' He turned to the other two.

'Out.'

They moved, Dillon got the door open, and she called, 'Sean, take care, for God's sake. Rashid is obsessed; he must kill you. In fact, he'll challenge you. It's like being back in the desert, Sean. He wants you for himself.'

She was crying. Arnold Bernstein pushed Dillon and Billy through the door and said, 'I'll be back, my love.'

Dillon said, 'She's taking it very hard. Why? She never approved of me.'

'You're such a smart man. You must be to have got away with killing people for the last thirty years. On the other hand, if you can't see why she's crying, my little Irish friend, then you really must be stupid.'

He walked away and Billy said, 'I think he means she likes you, Dillon.'

Dillon lit a cigarette. 'Yes, I did get that impression. Let's have a cup of tea. We'll hang around and maybe they'll let you see Harry before we leave.'

They went into the reception lounge, gave one of the girls an order and sat down.

Aidan Bell made it up from the river to the High Street and caught a cab to Mayfair. He walked the last few hundred yards to the back of the South

Audley Street house, where he rang the bell at the kitchen door. It was Kate who answered. Her face dropped.

'What's wrong?'

'Everything. Is he here?'

'Yes.'

'Then lead the way.'

She suddenly looked fearful. 'Where's Michael?'
