There was a good view of the street and, when I checked on the timetable of the postman, I was able to identify his route. Even without the telephone call Mackintosh was to make I ought to get at least fifteen minutes’ notice of his arrival. That point settled, I made a couple of expeditions from the office, pacing the corridor and timing myself. There really was no point in doing it without knowledge of the postman’s speed but it was good practice. I timed myself from the office to Gamage’s, walking at a fair clip but not so fast as to attract attention. An hour in Gamage’s was enough to work out a good confusing route and then work was over for the day and I went back to my hotel.
The next day was pretty much the same except I had the postman to practise on. The first delivery I watched from the office with the door opened a crack and a stopwatch in my hand. That might seem a bit silly; after all, all I had to do was to cosh a man. But there was a hell of a lot at stake so I went through the whole routine.
On the second delivery of the day I did a dummy run on the postman. Sure enough, it was as Mackintosh had predicted; as he approached Betsy-Lou’s door the letters for delivery were firmly clutched in hand and any box of Kodachromes should be clearly visible. I hoped Mackintosh was right about the diamonds; we’d look mighty foolish if we ended up with a photographic record of Betsy-Lou’s weekend in Brighton.
Before I left I telephoned Mackintosh and he answered the telephone himself. I said, ‘I’m as ready as I’ll ever be.’
‘Good!’ He paused. ‘You won’t see me again – apart from the hand-over of the merchandise tomorrow. Make a neat job of that, for God’s sake!’
‘What’s the matter?’ I asked. ‘Got the wind up?’
He didn’t answer that one. Instead, he said, ‘You’ll find a present awaiting you at your hotel. Handle with care.’ Another pause. ‘Good luck.’
I said, ‘Give my sincere regards to Mrs Smith.’
He coughed. ‘It wouldn’t do, you know.’
‘Perhaps not; but I like to make my own decisions.’
‘Maybe so – but she’ll be in Switzerland tomorrow. I’ll pass on your message when I next see her.’ He rang off.
I went back to the hotel, picked up a small package at the desk, and unwrapped it in my room. Nestling in a small box was a cosh, lead-centred and rubber-padded with a non-skid grip and a neat strap to go round the wrist. A very effective anaesthetic instrument, if a bit more dangerous than most. Also in the box was a scrap of paper with a single line of typescript: HARD ENOUGH AND NO HARDER.
I went to bed early that night. There was work to do next day.

Next morning I went into the City like any other business gent, although I didn’t go so far as to wear a bowler and carry the staff of office – the rolled umbrella. I was earlier than most because the first postal delivery of the day was before office hours. I arrived at Kiddykar Toys with half an hour in hand and immediately put on the kettle for coffee before inspecting the view from the window. The stallholders of Leather Lane were getting ready for the day’s sales and there was no sign of Mackintosh. I wasn’t worried; he’d be around somewhere in the neighbourhood keeping an eye open for the postman.
I had just finished the first cup of coffee when the phone rang. Mackintosh said briefly, ‘He’s coming.’ There was a click as he hung up.
In the interests of his leg muscles the postman had put in a bit of time and motion study on this building. It was his habit to take the lift to the top floor and deliver the letters from the top down on the theory that walking downstairs is easier than climbing them. I put on my coat and hat and opened the door a couple of inches, listening for the whine of the lift. It was ten minutes before I heard it go up, and then I stepped out into the corridor, carefully drawing the office door closed but not quite shut so that the least push would swing it open.
It was very quiet in the building at that hour and, as I heard the postman clattering down the stairs to the second floor, I retreated down the flight of stairs to the first floor. He hit the second floor and turned away from Betsy-Lou’s door to deliver the post to other offices. That was his usual routine and so I wasn’t worried.
Then I heard him coming back a few steps at a time, the intervals punctuated by the metallic bangs of swinging letterbox flaps. Just at the right time I came up the stairs and headed for the Kiddykar office which brought me facing him. I stared at his hands but there was no little yellow box to be seen.
‘Morning,’ he said. ‘Lovely day, isn’t it?’ He went past at a quick pace and I fumbled my way into the office, faking the opening of the door with a key. As I closed it behind me I found that I was sweating slightly; not much but enough to show that I was under tension. It was ridiculous, I suppose – I had only to take a little box away from an unsuspecting man, which should have been the easiest thing in the world and no occasion for nerves.
It was the contents of that box which set up the tension. A hundred and twenty thousand quid is a hell of a lot of money to be at stake. It’s rather like the man who can walk along a kerbstone unconcernedly and never put a foot wrong, yet let him try the same thing with a two-hundred-foot drop on one side and he’ll break into a muck sweat.
I walked over to the window and opened the casement, not so much to get fresh air as to signal to Mackintosh that the first delivery was a bust. I looked down into Leather Lane and saw him in his appointed place. He was standing before a fruit and vegetable stall prodding tomatoes with a nervous forefinger. He flicked his eyes up at the window then swung around and walked away.
I lit a cigarette and settled down with the morning papers. There was quite a while to wait before the second post.
Two hours later the telephone rang again. ‘Better luck this time,’ said Mackintosh, and hung up.
I went through the same routine as before – there was no harm in it as this would be a different postman. I waited on the landing just below the second floor and listened intently. It would be more difficult now that the building was inhabited and a lot depended on whether I could catch the postman alone in the corridor. If I could then it was easy, but if there was anyone else present I would have to grab the box and run for it.
Steady footsteps warned me that he was coming and I trotted up the stairs at the critical moment. I swung my head back and forwards like someone about to cross a street, and found that all was clear – no one in the corridor except for me and the postman. Then I looked at his hands.
He was carrying a bundle of letters and right on top of the bundle was a little yellow box.
I stepped right in front of him as he drew abreast of the Kiddykar office. ‘Have you anything for me?’ I asked. ‘I’m in there.’ I pointed to the door behind him.
He turned his head to look at the name on the door and I hit him behind the ear with the cosh, hoping to God he hadn’t an unusually thin skull. He grunted and his knees buckled. I caught him before he fell and pushed him at the door of the office which swung open under his weight, and he fell over the threshold spilling letters before him. The Kodachrome box fell to the floor with a little thump.
I stepped over him and hauled him inside, pushing the door closed with my foot. Then I grabbed the yellow box and dropped it into the innocuous brown box that Mackintosh had had specially tailored to fit it. I had to pass it on to him in the street and we wanted no flash of that conspicuous yellow to be seen.
In less than sixty seconds from the time I greeted the postman I was outside the office and locking the door on him. As I did so someone passed behind me in the corridor and opened the door of the Betsy-Lou office. I turned and went downstairs, not moving too fast but not dawdling. I reckoned the postman wouldn’t come round for two or three minutes,
