He pointed to a spot at the eastern side of the complex.
‘We will enter the building here-’
‘Why on the east side?’ I asked. ‘That’s between the building and the docks, Lord Dalgliesh’s centre of power. Isn’t it likely that there will be many of his men, there?’
Mr Ambrose threw me a look. ‘Which is exactly why we will come from this direction. He will not expect it. Do not interrupt me, Mr Linton. I don't wish to have to repeat myself.’ He tapped the point on the plan. ‘As I said, we will enter here-’
‘How exactly?’ I demanded. ‘In case you hadn’t noticed, there’s a wall in the way.’
His finger stopped tapping.
‘What did I say about not interrupting, Mr Linton?’
‘Excuse me, Sir. Carry on, Sir.’
‘The guards will be drawn off by a distraction on the western side of the building. We will have to climb over the wall, and thus penetrate into the inner courtyard.’
I still couldn’t see how we would be able to climb over a wall that was at least 24 feet high, but I held my tongue. From the way Mr Ambrose’s left little finger was twitching, I surmised this was not a time to rile him.
‘There will be guards on and in the inner building, too.’ His finger moved across the courtyard to a central, U-shaped building consisting of a large central part flanked by two wings. ‘They might not see us against the dark brick wall, but the courtyard is brightly lit. As soon as we attempt to cross it, we will be spotted.
‘So what do we do?’
Instead of my receiving another rebuke for having interrupted His Mightiness, it was Karim who answered this time.
‘Disguise ourselves,’ he grumbled, opening a bag and pulling out something bright red. It took me a few seconds to recognize uniforms of the Presidency Armies.
Suddenly, Mr Ambrose whirled around to face me.
‘But that’s it! Karim, you only brought two uniforms! So sh- he can’t come with us. Mr Linton, you…’
His voice trailed off as he saw Karim’s embarrassed expression. Then, his gaze wandered to the uniforms, of which, there was no doubt, there were three.
‘I thought,’ Karim growled, throwing a venomous look at Warren, who retreated a step or two, ‘that he would be coming with us.’
Mr Ambrose’s little finger twitched again, overcome by uncontrollable rage.
‘Fine,’ he said coolly, and turned back to the plans. ‘We will descend from the wall and hide behind this shed here, where brooms and tools are being kept, according to my information. There, we will change into guard uniforms, so we can cross the courtyard unmolested.’
With his forefinger, he tapped a spot marked with a longish rectangle and a question mark.
‘The door to the main compound may or may not be locked. My sources have not been able to determine that. But from what I know of Dalgliesh, it will be locked thrice and bound with chains. That, however, is no insurmountable problem.’
It seemed to be, to me, all right. I was just about to open my mouth when Mr Ambrose looked up from the map to throw me a cold glare.
I closed my mouth again.
‘Once inside, things will become more difficult,’ he continued.
Oh, so they’ve been easy up until now?
‘We do not know exactly where the file is. We believe it to be somewhere in this area.’ His finger moved to a red circle that centred on the upper left corner of the building. ‘This is where the office of the overseer was, back in the days when this was still a factory. It is, in all probability, where Dalgliesh’s office is situated now, and where the file is kept.’
He traced a route from the front door to the red circle. I could see faint lines on the old paper, marking a narrow hallway. ‘We will follow this corridor here, and hopefully will not encounter any guards. Yet, even if we do, they should take us for comrades and let us pass. The corridor will lead us straight to where we suspect Dalgliesh’s office to be. When we are there, we will take the file and leave the same way we came.’
‘But… won’t the file be behind locked doors?’
Mr Ambrose patted one of his mysterious bags. ‘Doors are not impenetrable, Mr Linton. What did I say about interruptions?’
‘So sorry, Sir.’
‘Karim?’
The Mohammedan stepped forward. ‘Sahib?’
‘Since you were so obliging as to provide three uniforms, you surely have also brought three of the cloaks?’
‘Certainly, Sahib.’
From his bag, Karim withdrew three mottled brown-and-grey cloaks. A strangled gasp came from Warren, and I remembered what Mr Ambrose had said about the special unit of riflemen under Lord Dalgliesh’s command.
