She had booked this visit a good few days before, and refused to believe that Agla had now taken her off the list. As far as María was aware, she was the only visitor Agla ever had. Yes, the visits did seem to trouble Agla, but each one always lasted the full allotted time, even though it invariably descended into arguments and quibbling. And yes, María always had a long list of questions, which Agla usually avoided answering, but her visits had to be about the only variation in the routine of being locked up. At least, María assumed that this was why Agla had put her name on the visitor list in the first place. It seemed to her highly unlikely that Agla had now changed her mind.

‘You can call tomorrow to book another visit,’ the prison officer said, tugging his shirt down over his paunch and stuffing it into his waistband. ‘Agla can’t have visitors today.’

‘Why not?’ María asked, leaning forwards, elbows on the table, driving home the point that she wasn’t about to leave.

‘She’s indisposed,’ the prison officer said, peering at the visitor list and scribbling a note on it.

‘I want to know why,’ María said. ‘Or let me call her myself, so she can tell me in person that she doesn’t want a visit.’

The prison officer sighed deeply.

‘Agla can’t see any visitors today. Try calling tomorrow.’

‘I’m an investigative journalist and I demand to know why prisoner Agla Margeirsdóttir isn’t available for a previously agreed visit. If I don’t get an explanation then I’ll have no choice but to take this to the Prison and Probation Administration.’

The prison officer sighed again, deeper this time, and his eyes rolled towards the ceiling.

‘Sweetheart, this isn’t Guantanamo Bay. We have a duty of confidentiality regarding the health of inmates, so all I can tell you is that Agla is unwell today, and that you can call tomorrow and book another visit.’

Now it was María’s turn to sigh. This was as far as she was going to get for the moment. There was no point in taking out her frustration on the prison officer. In reality, she didn’t suspect there was anything untoward about Agla’s absence; she was simply impatient. This time the questions on her list were all unusually urgent – she wanted to know about Agla’s links to Ingimar Magnússon and William Tedd, the Paris-based markets guru. She had come across both names during her investigation into Agla back when she had worked on economic crime for the special prosecutor. That had been in a previous life, before Agla had, indirectly, caused her to be sacked.
