'Maybe an old contact from his days as an active journalist '

'You don't really believe that.'

'Frankly, at the moment I don't know what to believe.'

'And why, I wonder, was it so important that you came up here?'

'No idea. I just do what I'm told – when it's Bob who tells me.'

A minute or two later the phone rang. 'Maybe it was this. We'll soon know. Yes,' he said, 'who is it?'

'Ronstadt left a few minutes ago. With his bag. He checked out.'

'You'd sooner not give me a name?'

'Right on the button. Good luck.'

Tweed put the phone down. He spoke as he went to a cupboard to fetch his packed bag.

'We're on our way. Whoever phoned had a smooth American voice. And I have to call the others.'

Paula was already on her way to the door, heading for her room. She stopped as Tweed's mobile started buzzing. He snatched it out of his pocket.

'Yes. Who's calling?'

'Me.' Marler's voice. 'Activity here. Drive over. Tell Bob to park at the edge of the Munsterplatz. He knows where…'

'That was Marler,' Tweed said and Paula left the room.

Tweed picked up the phone after dumping his bag close to his feet. He called Newman and Keith Kent. His message was the same to both of them.

'Now! Meet you with your bag outside the hotel. On our way to the car. I've kept the bill up to date, so paying won't take a moment.'

It seemed almost night as they drove away from the Colombi. In the white Audi they occupied the same positions as they had when driving from Basel. Newman was behind the wheel with Paula beside him, a map open on her lap. In the rear Tweed sat with Keith Kent. The traffic was light amid the gloom and soon Newman was approaching the Munsterplatz. He slowed down, dimmed his lights, stopped. Out of nowhere Marler appeared. He spoke quickly but concisely through Newman's lowered window.

'You got here just in time, I reckon. Ronstadt's black Audi has just left. Four men inside, including nice Jake, who's driving. The two Audis parked here also left, with seven men inside them. They're in front, with Ronstadt following. Bob, haven't you turned on the gizmo I bought in Geneva? The tracking device.'

No, I forgot. I've switched it on now.'

'How does it work?' Tweed asked, leaning forward. 'I hadn't even noticed it.'

Below the dashboard, Marler had earlier attached, with magnetic grips, a circular screen about six inches in diameter. Illuminated now, the glow showed it was divided by thin lines into the points of the compass. A round red light, about the size of a British five-pence piece, was moving very slowly in an easterly direction.

'That red light,' Marler explained, 'is Ronstadt. Earlier, Bob and I slipped back to where the Colombi parks cars. The signal-sending device was still on the roof of his car. It's about as big as one of those buttons you see on camel-hair coats. The signal travels up to a satellite which instantly returns it to your receiver, which you're looking at. To mine also. Luckily the device is black, so it merges with the colour of Ronstadt's car. Got it?'

'Just assume we do,' pleaded Paula. 'No more technicalities.'

'He can't move all that fast,' Marler went on. 'Heard a forecast. There's been another heavy fall of now in the Black Forest. Before we move off I'm Father Christmas.' He hitched up a long canvas holdall, started handing weapons through the window.

'One machine-pistol with ammo.'

'I'll take that,' said Paula. 'I've practised with them a lot recently down at the mansion in Surrey.'

'Walther 7.65mm automatics with spare mags.'

'I'll take one of those,' said Tweed, his voice grim. 'I remarked earlier we must exterminate this vermin.' Keith Kent accepted a Walther as Marler went on producing more.

'Grenades, smoke bombs…'

'Some for me,' called out Paula.

She stuffed them carefully inside her shoulder bag. She had already loaded the machine-pistol, laying it at her feet, the muzzle pointed at the door. Marler emptied his holdall, then said:

'Tweed, do you agree I drive ahead, Bob follows? Then if there's an ambush, which I think there will be – remember one Audi left hours ago – I'll deal with it. Bob drives on to maintain contact with Ronstadt and his convoy. If they reach their base wait until I catch you up. Four men went ahead earlier, there are seven with Ronstadt, which makes eleven thugs. You'd be out-gunned.'

'You might have trouble finding us,' Newman warned.

`No, I won't. I'm attaching another gizmo to your roof. It will show a blue light on my screen so I'll find you. That is if all this lot works. Modern technology. Dicey business.'

'I agree your strategy,' said Tweed.

'Then I'm off to the killing ground, as they say. The Black Forest.'

Marler reached up. Paula heard the magnetic clamps of the gizmo attach to the roof of their car. Marler ran off to where his white Audi was parked. Nield was already waiting in the front passenger seat. Butler sat hunched in the rear. Then Marler ran back to Newman's car.

'I forgot,' he told Newman through the window which had been lowered again. 'When that red light starts flashing you're almost on top of Ronstadt. Now I really must get moving..

'Paula,' said Tweed, 'sometimes Marler does have a grisly way of putting things.'

'You're referring to his use of the phrase "killing ground",' she replied. 'I don't care. I was thinking of poor Guy. I want to send the lot of them to where he's gone.'

They left Freiburg behind more quickly than Paula had expected. Soon they were driving over thick snow. As darkness fell the moon had risen, casting its vaporous glow over the lonely countryside. They entered a world of steep rolling hills covered with dense masses of fir trees, marshalled trunk to trunk like an invading army about to overwhelm them. Their branches and foliage, holding the snow, glittered like Christmas trees in the moonlight.

'You see now,' Tweed said to Paula, 'why I said it can be very beautiful. Are you listening to me?'

She was staring at the red light on the glowing screen. Her expression was almost brooding as though her thoughts were miles away., She shook her head; looked at Tweed.

'Sorry, I didn't catch what you said.'

'Doesn't matter. What were you pondering?'

'A lot of things. For one, why didn't the manager of the Colombi warn us Ronstadt had checked out? Especially after Kuhlmann had spoken to him.'

'Could be he was away from the hotel at the time. Or, if he was there, he might not have wanted to report the movements of one guest to another. If that was the case, I don't blame him. He has the reputation of the hotel to think of.'

'I was also wondering about the three thugs who travelled with Ronstadt. We never saw them while we were there.'

'He probably confined them to their rooms.'

'I do remember what you said now.' She looked out of the window. 'It is beautiful – but also sinister. And we haven't seen any traffic since we started out. Except for Marler's rear lights in the distance.'

'Something's coming towards us now in the opposite direction,' Newman remarked.

'What on earth is it, Bob?'

'Giant snowplough, clearing the snow. You have to give it to the Germans. They don't waste any time keeping the highways clear.'

'It's the first one we've seen,' she objected.

'Not surprising. It's out of season. Tourists – the skiing type – don't expect snow here as late as this. It's a really huge machine.'

'Bob, slow down,' Tweed ordered.

'Marler didn't.'

'I said slow down until we've passed it. Ronstadt is capable of any trickery.'

Tweed had lowered his window. He had his Walther in his hand. Paula automatically picked up the machine- pistol, laid it on her lap. The machine came closer, Newman had obeyed Tweed's command to slow down. Paula took a firmer grip on her weapon. The snowplough was moving very slowly and now the driver was visible. He appeared to be operating his machine innocently. Newman slowed down even more, cruising across the snow.
