‘So there is no real Winston Churchill? I find this most disappointing. ’

‘We’d be lost without George Cole,’ said Hugo Rune. ‘No one can do the voice as good as George.’ And Mr Rune perused his watch. ‘Ten minutes to go,’ he said.

The official-looking body who had vanished from our sight now reappeared with a clipboard held tightly between official-looking fingers. ‘Och braw the noo,’ he intoned. ‘If ye’ll sign this piece of paper, I’ll have-’

But he did not finish.

An explosion roared outside in the street and our latest cab went skywards.

Having done the instinctive duckings, Mr Rune and I returned to our feet and viewed the devastation without.

‘Do I see some kind of pattern emerging here?’ I asked. ‘Has God got it in for taxis, or is some basic engine design fault bringing itself to the fore?’

Hugo Rune once more perused his watch. ‘That one was a little too close for comfort,’ he said. ‘You will pardon me, Rizla, whilst I take myself off to the Gents.’

And with that he did so, leaving me to stand around and wait. But I really did not mind too much about the waiting, as it did give me an opportunity to see if I could spy out any more stars of the wireless set.

And would not you know it, or would not you not, I spied out the great Harry ‘put on your plimsolls, Mother, I’ve got a dose of the runs’ MacKentyre. Charlie ‘if it looks like a ferret and smells like a ferret, it shouldn’t be stirring my tea’ MacAlistair. And Jimmy ‘boil up the orange sauce, Uncle, I’ve just been bowled out for a duck’ MacMackMack. And-

‘Cease, Rizla,’ said Hugo Rune, returning. ‘It is neither big, nor clever. But, say, isn’t that Leslie “if God is dog spelled backwards, then what the kcuf is taht?” Tomlinson?’

‘No,’ I said. ‘Though it does look like him. Are you all better now?’

‘Better now?’ said Hugo Rune. ‘Ah, I see what you mean. The taking myself off to the Gents. Just needed to highlight my cheekbones – what do you think?’

‘I think we have become caseless and plotless and lost,’ I said. ‘And now I know that Winnie is not Winnie, I think I would just like to go home and have a good sulk.’

‘And miss all the excitement?’

I did head-bobbings to signify ‘weighing-up’. ‘We nearly got beaten to pulp at the Savoy Grill and the two cabs we requisitioned have exploded. Let us say that I have had sufficient excitement for today and perhaps a case will present itself tomorrow.’

‘It has already presented itself,’ said Hugo Rune. ‘You have failed to put two and two together. I, however, have done that very thing. Come, Rizla, destiny awaits.’

At precisely three of the afternoon clock, myself and Mr Rune, George Cole, a radio producer called Neil and a number of probably nameless secret service fellows in morning suits and bowler hats gathered in a green room on the second floor of Broadcasting House. With a gravity that was little less than ludicrous, Hugo Rune clicked open the briefcase and passed a sheet of paper to the pretend prime minister.

George Cole examined this, turned the sheet over and looked at the back and then turned it front-wise again. ‘And is this all there is?’ he asked, in the voice of Winston Churchill. ‘Nothing about fighting them on the beaches and in the fields and over the cricket greens and up the back passages or whatnot?’

Hugo Rune shook his head. ‘Only what you see, I’m afraid.’

‘I could perhaps put in something about “some chicken, some neck”, or how this was “their finest hour”. What exactly is my motivation? Should I pad it out with a bit of King Lear?’

‘Best to stick to what it says on the paper,’ said Hugo Rune. ‘But there is one thing you could do.’

After we had left Broadcasting House, I thanked Hugo Rune.

‘That was very decent of you,’ I said, ‘asking him to sign his autograph for me.’

‘For you?’ said the Perfect Master. ‘For me, if you please.’

But he was only joking.

‘So,’ I said, ‘should we listen to a wireless set and hear what this highly important message to the nation might be?’

But Hugo Rune shook his head. ‘We should be getting on with the exciting stuff,’ he said. ‘And to do this we must return to the Ministry of Serendipity.’

‘I really have lost the plot,’ I said. ‘Would you care to explain?’

‘All in good time, young Rizla. But see – an unattended cab. I think you will find that your key fits the lock. Mornington Crescent, please. And as fast as you can.’

I halted the cab outside the Lyons Corner House, wherein lay the lift to the underground Ministry. I made to leave the cab, but Mr Rune said no.

‘Stay here, Rizla, and keep the engine running. And be prepared to drive at speed the moment I return.’

And with that said Hugo Rune left the cab and vanished into the Lyons Corner House. I sat idly brumming the engine and tinkering about with things that did not belong to me. This tinkering led to me opening the glove compartment and finding to my joy not only gloves, but a service revolver as well. I twirled this dangerously on my finger and did aimings and the mouthings of phrases such as, ‘Take a roadside rest, Fritz,’ and, ‘Cop this, Adolf, kapow kapow kapow.’

And then suddenly Hugo Rune returned, jumped into the rear seat and shouted, ‘The cab up ahead, the one just leaving the corner, after it!’

‘You would not care to explain?’ I asked.

‘After it, Rizla!’ cried Mr Hugo Rune.

And so I gave chase. And clearly I was giving chase, because the cab across the street took off at speed and, with ne’er a care for a passing cleric on a bike, did swervings and acceleratings too.

‘Faster, Rizla, faster. We can’t let this blighter escape.’

‘I would really like it if you told me what is going on,’ I said. But Hugo Rune cried, ‘Faster!’ so I put the hammer down. Well, pressed my foot to the elegantly designed accelerator pedal anyway.

We passed around Piccadilly Circus, through Leicester Square, Trafalgar Square and up the Royal Mall towards the palace.

‘Faster, Rizla, faster and run him off the road.’

‘What?’ I said. ‘I cannot,’ I said.

‘Just do it!’ shouted Hugo Rune.

And I put my foot down as far as it would go and my cab drew level with the other cab. And would not you know it, or would not you not, that other cab was being driven by Hugo Rune’s arch-enemy, the ever evil bad Count Otto Black.

And in the back of that cab sat Mr McMurdo, wearing a fearsome expression.

‘Off the road with them, Rizla,’ shouted Mr Rune. ‘Grind them into a tree.’

So I took a deep breath and swung the wheel and our cab struck their cab a devastating blow. There were showerings of sparks and grindings of metal and the cabs’ running boards and wheel arches got sort of locked together, which caused them to leave the road and hurtle towards a very large tree indeed.

And yes, things really do seem to happen in slow motion in situations such as this. And what I saw surprised me all the more because it happened as if so slowly.

The entire front part of the other taxicab detached itself from the rest of the vehicle and rose into the sky.

It was the count upon his flying motorcycle. The rear section of his now driverless cab continued on at speed and ploughed into the tree. A terrible explosion occurred that freed the cab that Mr Rune and I were travelling in and allowed it to grind to a halt some hundred yards beyond. With both of us mostly unscathed.

And when I felt myself able to speak again, I raised my head from between my legs and managed to blurt out a, ‘What was that all about?’

‘Infamy and trickery,’ said Hugo Rune.

‘And Mr McMurdo,’ I said. ‘Oh dear. Was Count Otto kidnapping him? He was still in the cab, he must surely be-’
