Andy McNab - Zero hour

It was going to be a nightmare to recce in these narrow roads. There was no cover and no reason to be here. I couldn't just stand in the middle of a lane and study my target. I'd be able to do one walk-past, maybe two at a push, as long as I came back in an hour or so from a different direction.

There was the odd shop, and yet another pharmacy. I went in for more aspirin but also discovered something else I was after. Pure alcohol. Well, 95 per cent pure. It wasn't for drinking, but the sort old people use as an antiseptic. I bought two 500ml plastic bottles of the stuff and crossed it off my mental shopping list.

Eventually, I turned left onto Westerstraat. It seemed out of place somehow, an eighty-metre-wide boulevard among the lanes. There was even a central reservation big enough for two cars to park nose to nose.

A lot of the expensive-looking seventies and eighties apartment blocks boasted shops on their ground floor. They were independents rather than chains: a bike shop, a couple of small supermarkets, an Internet cafe next to a mattress store, a newsagent.

118 was down at the end of the street, as Bradley had promised. I saw a sign for an Internet cafe that turned out to be more of a 7/11. There were four or five banks of screens. You paid in a slot machine and could order food and drink, even buy music CDs.

I logged on with five euros for thirty minutes, then hit Google Earth and Street View for my virtual tour of the target. I could see the striped canopy that ran outside the cafe. The target house's pitched roof was immediately to its left. It was narrower than those on either side of it. It backed onto a square, with four similarly proportioned terraces lining each side. I clicked the arrows anti-clockwise along each of them, looking for a gap between the buildings. I finally found an archway. I could imagine a coach and horses rattling through to the stables after dumping the good burghers of Noordermarkt outside their front doors. The whole area had now been segmented, with fences and walls bordering private parking spaces and places to store industrial-sized wheelie bins.

I soaked up the imagery. This was the only known location for the target, and not a bad one. At least it wasn't exposed to the real world, unlike the cafe next door. Whatever went on inside was kept inside. For a while, anyway.

I wanted to get into 118 later today, to work out the best access route when I came back later to finish the job. I needed to check out the alarm system, and might even be able to adjust a window or door lock to make re-entry a whole lot easier. Once I'd sorted the competition, I'd have bought myself the time to get everything in place to hit the silo. My number-one priority was still the girls, whatever Tresillian had in mind.

I Googled Anne Frank's house and a couple of galleries to mix the session up a bit, then deleted my history and closed down, making sure the log-off really did log off.

The white cafe with striped canopies and a blue door was open for business on the junction ahead. The canal was less than a hundred metres further on. White plastic sheeting protected a run of stalls in a small, brick-paved square between the two. There were no green Passats in sight.

I crossed the road opposite 118 so I had the clearest possible view of its front elevation. A small glass porthole protected by a metal grid was set into the solid wood front door. The windows on all three floors were wooden-framed and double-glazed. I couldn't see lights or movement behind any of them.

I spotted two keyholes: Union cylinders, probably with night latches. They wouldn't normally be a problem to defeat; I could just buy a couple of other Unions and doctor the keys. But the road was constantly busy, and I didn't fancy fucking around with them in front of an audience: people were having a beer and a pizza just a couple of metres away. With any luck they'd have the same kit on the back door as well.

The entry point into the square was about a hundred metres up Noordermarkt. The street was much narrower, with houses and shops on both sides. Most of them seemed to be selling candles, linen and anything else that was white. The good burghers' coaches would have been rolling in and out of here pretty much all the time back in the eighteenth century, but these days they were a bit more reluctant to welcome uninvited visitors. A pair of wrought-iron gates now stood guard a few metres in. They were surrounded by vines and flowers, but weren't just there for decoration.

To the left of the archway, within arm's reach of a driver, was a bank of buttons on a steel box and a numbered keypad. To the right of the main gates was a smaller one for pedestrians, with its own digital entry box mounted on a steel panel on the latticework frame. There are ten thousand possible combinations to a four-figure code. I'd be here all week trying to find the right one; that was the whole point of them. I needed a simpler solution: I needed to find out how the guys on the inside of the square – and their welcome guests – managed to get out.

I pulled the map out of my pocket and gave my head a bit of a scratch as I pretended to get my bearings. The main exit would be triggered from the inside by a detector as a car approached the gate. But how did they open the pedestrian gate from the inside? It wouldn't need a code: they'd have a simple push-button arrangement of some sort. Was the button on the back of the electric lock? Was it set back, on the wall? I couldn't see much in the shadows. I gave the steel panel behind the entry keypad another look. It had to be there for a reason. It had to be there to stop anyone on my side of the fence getting access to the exit button.

I couldn't risk going any further in – I might just as well be wearing a striped T-shirt and a stocking over my head. I wandered back onto Noordermarkt and took the first left. I wanted to do a complete 360 of the square. There might be a less secure route in. I hung another left and was soon back on Westerstraat. I'd found nothing.

I crossed the road and carried on back towards the target, keeping my eyes open for a newly parked Passat or any change on-target. Was an extractor flue knocking out steam perhaps, because somebody had come home and jumped in the shower?

Nothing.

It was only two o'clock and another three or four hours until last light.

I carried on towards the canal, following signs that showed a little man walking towards Anne Frank's house. Not that I was going to see it – not yet, anyway. I was heading for the centre, the area of town I knew well, the bit that was full of bars and whorehouses, backpackers and tourists. That was where I'd blend in best, and where I could buy what I needed to get this bit of business done without anyone remembering me.

I crossed the canal and stopped at an ATM. I drew out three hundred euros on Nick Smith's MasterCard, as you would do if you were bumbling about the city centre, planning a bit of souvenir shopping and maybe a mooch around the red-light district.

I carried on to Damrak, the main drag from the central train station. It was a blur of trams and cars. Bells jangled. Cyclists wove between pedestrians. The place was packed, mainly with drug-dealers whispering, 'Weed? Cocaine?' to anyone who came within reach.

There were a couple of camping shops. A lot of the visitors here were backpackers. I went into the biggest, and therefore with luck the least friendly, and bought myself a black fifty-five-litre Bergen. Into it went a hard plastic knife-fork-spoon set any Scout would have been proud of and a Russian-doll type assortment of cheap aluminium cooking pans of the kind he'd make rehydrated stews in that nobody wanted to eat.

I also bought a twenty-litre plastic water container, the sort that concertinas down to save space, and a roll of silver gaffer tape big enough to stick the world back together. The last bit of kit I bought from this place was a portable stove in a plastic briefcase, fuelled by aerosol cans rather than Camping Gaz canisters.
