‘I’m not going back to her.’

‘Where are you staying – Nick and Ilsa’s?’

‘No. I’ve got a little place in Hammersmith’ (the first place that occurred to him, associated, now, with homelessness). ‘Bedsit.’

‘Oh Stick… come and stay with us!’

He had a fleeting vision of the all-blue spare room, and Greg’s forced smile.

‘Luce, I’m happy where I am. I just want to get on with work and be on my own for a bit.’

It took him another half-hour to shift her out of his office. She felt guilty that she had lost her temper; apologised, then attempted to justify herself, which triggered another diatribe about Charlotte. When she finally decided to leave, he helped her downstairs with her bags, successfully distracting her from the boxes full of his possessions that still stood on the landing, and finally depositing her into a black cab at the end of Denmark Street.

Her round, mascara-streaked face looked back at him out of the rear window. He forced a grin and a wave before lighting another cigarette, and reflecting that Lucy’s idea of sympathy compared unfavourably with some of the interrogation techniques they had used at Guantanamo.

Robin had fallen into the habit of buying Strike a pack of sandwiches with her own, if he happened to be in the office over lunchtime, and reimbursing herself from petty cash.

Today, however, she did not hurry back. She had noticed, though Lucy had seemed oblivious, how unhappy Strike had been to find them in conversation. His expression, when he had entered the office, had been every bit as grim as the first time they had met.

Robin hoped that she had not said anything to Lucy that Strike would not like. Lucy had not exactly pried, but she had asked questions to which it was difficult to know the answer.

‘Have you met Charlotte yet?’

Robin guessed that this was the stunning ex-wife or girlfriend whose exit she had witnessed on her first morning. Near-collision hardly constituted a meeting, however, so she answered:

‘No, I haven’t.’

‘Funny.’ Lucy had given a disingenuous little smile. ‘I’d have thought she’d have wanted to meet you.’

For some reason, Robin had felt prompted to reply:

‘I’m only temporary.’

‘Still,’ said Lucy, who seemed to understand the answer better than Robin did herself.

It was only now, wandering up and down the aisle of crisps without really concentrating on them, that the implications of what Lucy had said slid into place. Robin supposed that Lucy might have meant to flatter her, except that the mere possibility of Strike making any kind of pass was extremely distasteful to her.
