'Miss Atterdine?'

She looked up from her typewriter. It was Mr Comeau, one of the under-secretaries in the ministry, a neat middle-aged man with a trimmed moustache and a nervous manner that was at once shy and punctilious. He asked her to come into his office.

He sat at his desk and searched through his papers.

'Please sit.'

She did so. He was a proper man, Mr Comeau, never acting in a superior or dismissive manner – as some of the other undersecretaries did as they thrust their documents at the typists and issued their instructions as if they were talking to automata – but there was something melancholy about him, too, about his neatness, his propriety, as if it were his guard against a hostile world.

'We have your application for the London posting here. It's been approved.'

'Oh, good.' She felt a heart-thud of pleasure: something would happen now, she sensed her life taking a new direction again, but she kept her face expressionless.

Comeau told her there was a new draft of five 'young women' from the Ottawa ministries leaving St John on 18 January for Gourock in Scotland.

'I'm very pleased,' she said, thinking she must make some comment. 'It's very important to me-'

'Unless…' he interrupted, trying for a playful smile and failed.

'Unless what?' Her voice was more sharp and abrupt than she meant it to be.

'Unless we can persuade you to stay. You've fitted in very well here. We're very pleased with your diligence and ability. We're talking about promotion, Miss Atterdine.'

She was flattered, she said, indeed she was surprised and overwhelmed, but nothing could persuade her otherwise. She alluded, discreetly, to the unhappy experiences in British Columbia, how all that was behind her and she wished simply to go back home now, home to her widowed father, she added, throwing in this new biographical information spontaneously.

Mr Comeau listened, nodded sympathetically, said he understood, and told her that he too was a widow, that Mrs Comeau had died two years ago and that he also knew that loneliness her father must be experiencing. She realised now where his air of melancholia originated.

'But think again, Miss Atterdine,' he said. 'These Atlantic crossings are dangerous, there's risk involved. They're still bombing London. Wouldn't you rather be here in Ottawa?'

'I think my father wants me back,' Eva said. 'But thank you for your concern.'

Comeau raised himself from his chair and went to look out of the window. A small rain was spitting on the glass and he traced the squirming fall of a raindrop on the pane with his forefinger. And Eva was instantly back in Ostend, in Romer's office, the day after Prenslo, and she felt a giddiness overcome her. How many times a day did she think of Lucas Romer? She thought of him deliberately, wilfully all the time, thought of him organising the search for her, thought of him thinking about her, wondering where she was and how to find her, but these inadvertent moments when memories pounced on her took her unawares and were overwhelming.

Comeau was saying something.

'I'm sorry?'

'I was wondering if you had plans for the Christmas holiday,' he said, a little shyly.

'Yes, I'm staying with friends,' she said, instantly.

'I go to my brother's, you see,' he continued as if he hadn't heard her. 'He has a house near North Bay, on the lake.'

'Sounds wonderful, unfortunately-'

Comeau was determined to make this invitation, overriding all interruptions. 'He has three sons, one of them married, a very nice family, eager, friendly young people. I wondered if you'd like to join us for a night or two, as my guest. It's very relaxed and informal – log fires, fishing on the lake, home cooking.'

'You're very kind, Mr Comeau,' she said, 'but I've already made all the arrangements with my friends. It wouldn't be fair on them to cancel at such short notice.' She put on a frustrated smile to console him a little, sorry to let him down.

The sadness crossed his face again – he had had his hopes high, she realised. The lonely young English woman who worked in the typing pool – so attractive, leading such a drab, quiet life. The London transfer would have galvanised him, she knew, made him act.

'Yes, well, of course,' Comeau said. 'Perhaps I should've asked you earlier.' He spread his hands abjectly and Eva felt sorry for him. 'But I had no idea you would be leaving us so soon.'

It was three days later when Eva saw the car for the second time, a moss-green '38 Ford parked outside the Pepperdines' house. Before that it had been outside Miss Knox's and Eva knew the car belonged to neither Miss Knox (an elderly spinster with three terriers) nor the Pepperdines. She walked quickly past it, glancing inside. There was a newspaper and a map on the passenger seat and what looked like a thermos flask in the door pocket on the driver's side. A thermos flask, she thought: someone spends a lot of time in that car.

Two hours later she went out 'for a stroll' and it was gone.

She thought long and hard that night, telling herself initially that if she saw the car a third time she would move out. But she knew that was wrong, remembering her Lyne training: when the anomaly appears react to it immediately was the rule – a Romer rule. If she saw it for a third time it would almost definitely be sinister and by then perhaps too late, as far as she was concerned. That night she packed her small grip and looked out of her dormer window at the houses opposite and wondered if there was a BSC team already installed there waiting for her. She put her grip by the door, thinking how light it weighs, how few possessions I have. She did not sleep that night.

In the morning she told Mr and Mrs Richmond that she had to leave urgently – a family matter – and was going back to Vancouver. They were sorry to see her go, they said, but she had to understand that at such short notice they couldn't possibly reimburse the residue of her month's rent paid in advance. Eva said she understood, completely, and apologised for any inconvenience.

'By the way,' she asked, pausing at the door, 'has anyone left any messages for me?'

The Richmonds looked at each other, consulting silently, before Mrs Richmond said, 'No, I don't think so. No, dear.'

'No one's called round to see me?'

Mr Richmond chuckled. 'We had a young man drop by yesterday asking to rent a room. We told him it was ladies only – he seemed very surprised.'

Eva thought: it's probably nothing, a coincidence, but she suddenly wanted to be away from Bradley Street.

'If anyone does call say I've gone back to Vancouver.'

'Of course, dear. Take care now, it's been lovely knowing you.'

Eva left the house, turned left instead of her usual right, and briskly walked a meandering, convoluted mile to a different bus stop.

She moved into the Franklin Hotel on Bank Street, one of Ottawa's largest, a functional, modest establishment with over 300 rooms 'completely fireproof and all with shower and phone' but no restaurant or coffee shop. However, even with her single room at three dollars a night, she realised she was going to run out of money. There were no doubt cheaper hotels and more frugal lodgings to be had in Ottawa but she required the security and anonymity of a large central hotel. She had a little over three weeks to go until her voyage back to Britain: she just needed to bury herself away.

Her room was small, plain and on the seventh floor and through a gap in the buildings opposite she could see the green expanse of the Exhibition Grounds and a swerve of the Rideau River. She unpacked and hung her few clothes in the wardrobe. The one advantage of the move was that she could at least walk to work and save on bus fares.

But she kept wondering if she had done the right thing, if she had been too jumpy, and that the very suddenness of her move from the Richmonds might have signalled something itself… A strange car in a suburban street – what could be so alarming about that? But she reminded herself that she had chosen Bradley Street and the Richmond Guest House precisely because its location made it easy to spot anything unusual occurring. Everybody knew everyone and knew everyone's business on Bradley Street – it was that kind of neighbourhood. And who was the young man who had failed to read the 'Ladies Only' rubric on the guest-house sign? A careless traveller? Not a policeman, she thought, for a policeman would have simply identified himself and asked to see the register. Someone from BSC, then, instructed to check out the hotels and guest-houses in Ottawa. Why Ottawa, she reasoned further, why not Toronto? How could anyone guess or deduce she had gone to Ottawa? And so the questions continued, badgering her, sapping her energy. She went to work as usual, typed letters and documents in the typing pool and came home to her room. She barely inhabited the city. She bought sandwiches on her way home from work, stayed in her room with its view of the Exhibition Grounds and the Rideau River and listened to the radio, waiting for Christmas and 1942 to arrive.
