‘What has this to do with Special Crimes, sir?’

‘“You too, be patient.” James, chapter five, verse eight.’

A wash of well-being came over Quinn. Hearing Sir Edward quote the Bible, it seemed that the proper order of things had been restored. The world was back in balance.

‘Our masters wish you to keep an eye on German nationals.’

‘All German nationals, sir?’

‘That would be asking rather a lot, even of you and your redoubtable men, Quinn. The brief is to be alert for anything that seems suspicious, in connection with any German nationals who come to your attention.’

‘It seems a rather loose brief, if you will forgive me for saying so, Sir Edward.’

‘Nonsense. Go out there. Keep your eyes open. Ferret around. If necessary, infiltrate yourselves into the circles in which these individuals move.’

‘Are we to assume German identities?’

‘Do you speak German, Quinn?’

‘No, sir.’

‘Do any of your men?’

‘Not that I am aware, sir.’

‘Then I advise against that particular course of action.’ Another twinge of pain racked Sir Edward’s frame. Quinn recognized it as a sign that Sir Edward wished to draw the interview to a close. The commissioner gave a terse concluding nod, but was stayed by something he saw in Quinn’s expression. ‘You look perplexed, Quinn.’

‘It is merely that I am not sure how to go about this.’

‘I’m sure you’ll think of something. “Be not dismayed.” Isaiah, chapter forty-one, verse ten. Or we might quote Jeremiah, chapter one, verse seventeen. You know that one, of course, Quinn?’

‘I … I seem to have temporarily forgotten it.’

‘“Thou therefore gird up thy loins, and arise.”’

Quinn suddenly found Sir Edward’s fondness for biblical quotes less endearing than he had a moment earlier.

Sir Edward closed the file on his desk and pushed it towards Quinn. ‘A sordid little case, that one. Too many people dead, as usual, Quinn.’

‘I cannot be …’

‘Don’t worry. I wasn’t blaming you. Not this time. We cannot always be held responsible if people insist on going around killing one another. But at least we can close the file on it now. Although there was one curious epilogue to the case that you may be interested to hear about. It signifies nothing, I am sure.’

Quinn sat up sharply in his seat. ‘What has happened?’

‘Oh, it appears that the West Middlesex mortuary was broken into last night. One of the bodies was tampered with. By a strange coincidence, it happens to have been the body of the second victim in your House of Blackley case. Edna Corbett. Some ghoulish prankster, I’m sure. Of no significance, as I say.’

‘What do you mean by tampered with?’

‘A body part was removed.’

‘Which body part?’

‘Oh, for goodness’ sake, Quinn! If I had known you were going to react like this, I should never have told you.’

‘Was it an internal organ, sir?’

‘I really don’t want to sit here while you engage in gruesome speculation. So I will tell you. It was one of the eyes.’

‘Should I look into it, sir?’

‘Look into the missing eye? I don’t see how you can, Quinn. No, put it from your mind. That case is over. Germans. That’s the thing. Keep your eye out for Germans.’ Sir Edward’s renewed grimace had about it the air of finality. Quinn felt himself dismissed.

SIX

There was no place Inti liked better than this. The soft red glow from the safety light was his whole world. Nothing existed beyond its quivering sphere. All pain and confusion were banished to the darkness beyond. There were no memories here. Only the sense of miracles forming in the chemically pungent darkness.

Each time he entered the darkroom, he was reborn.

He watched his uncle Diaz work with practised speed. Diaz was a wizard. In truth, Diaz was many things. But when it came to coaxing out the secrets he had trapped in the light-sensitive layer of emulsion on his strips of film, he was a wizard. It went without saying that Inti loved his uncle, with a fierce, unwavering love forged under a relentless sun, and in a heartless landscape. The natural bonds were strengthened by his awareness of all that Diaz had done for him. But the feelings he felt when he watched Diaz operate in the darkroom came close to awe.

Diaz always did his own processing and printing. He had taught Inti that it was an essential part of the kinematographic cameraman’s art. Everything depended on the interaction between chemicals and time. Each part of that precarious marriage had to be carefully controlled. Minute adjustments could be made to produce particular effects; it was up to the cameraman, Diaz insisted, to make these decisions. They could not be surrendered to anyone else.

The formulation of the developer was one of Diaz’s own devising. The exact proportions of active ingredients to water had evolved over years of trial and error, together with the temperatures at which they were mixed and subsequently maintained in the glazed earthen-ware trough.

These were trade secrets which Diaz refused to impart to any of his friends, let alone a rival. But it was a sign of the bond that existed between uncle and nephew that he had passed his precious formulae on to Inti. Nothing was written down. Fully conscious of the privilege that had been bestowed on him, Inti had memorized the relative weights of metol, hydroquinone, soda sulphite, soda carbonate and potassium metabisulphite that had to be mixed to every thirty litres of water.

Inti had also been initiated into the mysteries of the stopwatch. Today, as always, it was his job to keep his eye on the dashing second hand and call out the minutes to his uncle.

First, though, Diaz opened the box of steel pins. In the darkroom’s sombre glow, they looked like fine shards dipped in blood. Diaz drew out two and pinned them to the lapel of his lab coat. Now he opened the take-up box that was lying on the work bench and teased out the end of the exposed film.

Sometimes Inti felt his uncle would have been able to perform the operation blindfold. Certainly the necessity to do everything in that parsimonious half-light was no handicap to him. He must have had magical eyes in the tips of his fingers. From somewhere, a pair of scissors had appeared in one of his hands, their blades burnished with a ruby fire. He moved with an impressive combination of speed and precision to cut off two lengths of the exposed film, each of about fifteen centimetres. The hands shuffled in the darkness, returning the scissors to their appointed place out of sight, closing the front of the take-up box, and – with a nod to Inti for him to begin the timing – plunging the two lengths of film into the bath of developer. It was all executed in one fluid motion.

Everything took place in silence, apart from the occasional liquid plinking as Diaz gently stirred the development fluid. There was no need for instructions to be passed between them. They had worked together like this many times.

When it came to other matters, it was not that they had nothing to say to one another, but rather that there were no words for the things that needed to be said.

They limited themselves to banal exchanges. And never spoke of what was dearest and most troubling to them.

Only once had his uncle referred to such matters. Diaz had perhaps caught something in his nephew’s expression. He had placed his hand on his nephew’s shoulder and said quietly and simply: ‘We shall make them see, Inti. One day we shall make them see.’

Then he had nodded once and removed his hand from Inti’s shoulder.

For such men, in such circumstances, it is good to have an absorbing task that requires intense concentration and can be carried out in near darkness.

But it was strangely appropriate, this silence of theirs. A mute conjuring of silent, flickering ghosts from out of the coiled void.
