      Mantis said nothing more about the tattoo. Carradine was told that if he spotted the woman, he was to approach her discreetly, ensure that their conversation was neither overheard nor overseen, and then to explain that he had been sent by British intelligence. He was also to pass her a sealed package. This would be delivered by the Service before he left for Morocco.

      ‘I’m assuming I can’t open this package when I receive it?’

      ‘That is correct.’

      ‘Can I ask what will be inside it?’

      ‘A passport, a credit card and a message to the agent. That is all.’

      ‘That’s all? Nothing else?’

      ‘Nothing else.’

      ‘So why seal it?’

      ‘I’m not sure I understand your question.’

      Carradine was trying to tread the fine line between protecting himself against risk and not appearing to be apprehensive.

      ‘It’s just that if my bags are searched and they find the package, if they ask me to open it, how do I explain why I’m carrying somebody else’s passport?’

      ‘Simple,’ Mantis replied. ‘You say that it’s for a friend who left it in London. The same friend whose photo you’re carrying in your wallet.’

      ‘So how did she get to Morocco without a passport?’

      Mantis took a deep breath, as if to suggest that Carradine was starting to ask too many questions. ‘She has two. One Spanish, the other British. OK?’

      ‘What’s my friend’s name?’

      ‘Excuse me?’

      ‘I need to know her name. If it’s on the passport, if I’m carrying her picture around, they’ll expect me to know who she is.’

      ‘Ah.’ Mantis seemed pleased that Carradine had thought of this. ‘The surname on the passport is “Rodriguez”. Christian name “Maria”. Easy enough to remember.’

      ‘And mundane enough not to draw attention to itself.’

      ‘It does have that added dimension, yes.’

      They remained at the Lisson Grove flat for another half-hour, going over further practical details of Carradine’s trip, including protocols for contacting Vauxhall Cross in the event of an emergency. Mantis insisted that they meet at the flat when Carradine returned from Marrakech, at which point he would be debriefed and given payment, in cash, for any expenses he had run up in Morocco.

      ‘Feel free to stay somewhere decent in Casablanca,’ he said. ‘We’ll cover your costs, the extra flight as well. Just keep accurate receipts for the bean counters. They’re notoriously stingy when it comes to shelling out for taxis and train tickets.’

      As Carradine was leaving, Mantis handed him two envelopes, each containing €1,500. There was no limit to the amount of foreign currency he was permitted to bring into Morocco and Mantis did not think that €3,000 would be considered suspicious. He told Carradine that the sealed package containing the passport and credit card would be delivered to his flat in Lancaster Gate the following day, as well as the novel which was to be used as a book cipher. Mantis reiterated the importance of leaving the sealed package intact, unless Carradine was instructed to open it by law enforcement officials in the UK or Morocco. He did not give an explanation for this request and Carradine did not ask for one. Carradine assumed that the package would contain sensitive documents.

      ‘Good luck,’ Mantis said, shaking his hand as he left. ‘And thanks for helping out.’

      ‘No problem.’

      Carradine walked out onto Lisson Grove in a state of confusion. He was bewildered by the speed with which Mantis had acted and strung out by the painstaking assimilation of so much information. It seemed bizarre that he should have been asked to undertake work on behalf of the secret state – particularly after such a cursory meeting – and wondered if the entire episode was part of an elaborate set-up. Clearly the content of his novels, the depictions of tradecraft, his observations about the burdens of secrecy and so forth, had convinced the Service that C.K. Carradine was possessed of the ideal temperament to work as a support agent. But how had they known that he would agree so readily to their offer? While working for the BBC in his twenties, Carradine had spoken to three veteran foreign correspondents – two British, one Canadian – each of whom had been tapped up by their respective intelligence services overseas. They had turned down the opportunity on the basis that it would interfere with the objectivity of their work, undermine the relationships they had built up with local sources and potentially bring them into conflict with their host governments. Carradine wished that he had shown a little more of their steadfastness when presented with the dangled carrot of clandestine work. Instead, perhaps because of what had happened to his father, he had demonstrated a rather old-fashioned desire to serve Queen and country, a facet of his character which suddenly seemed antiquated, even naive. He was committed to doing what Mantis had asked him to do, but felt that he had not given himself adequate protection in the event that things went wrong.

      Still in a state of apprehension, Carradine took a detour on the way home, purchased a roll of masking tape and found an Internet café in Paddington. He wanted to be certain that Mantis was a bona fide Service employee, not a Walter Mitty figure taking advantage of him either for his own amusement or for some darker purpose which had not yet been made clear.

      The café was half-full. Carradine stood over a vacant computer, tore off a small strip of the masking tape and placed it over the lens at the top of the screen. The computer was already loaded with a VPN. In his most recent novel, Carradine
