There were two flats off the top landing at 44 Scotland Street – that belonging to Domenica Macdonald and that belonging to Antonia Collie. Of the two, Domenica’s flat was the better-placed: its front windows gave a view of a slightly larger slice of Scotland Street and allowed a glimpse, too, of the distinguished roofs of Drummond Place. Antonia’s view, although pleasant enough, was mainly of the corner of Royal Crescent. And although the symmetry which inspired the architecture of Scotland Street and indeed of the entire New Town should have led to both flats having the same number of rooms, Domenica had one more room than her neighbour. This was strange, and could only have been explained by the carrying out in the mists of the past of a structural rearrangement within the building; a wall had been knocked through and a room had been taken from Antonia’s flat and added to Domenica’s. Such modifications were not without precedent in the area, and had occasionally been carried out when two adjoining flats had ended up in the ownership of the same landlord.

When Antonia had bought the flat from Bruce Anderson at the end of his first Edinburgh sojourn, he had said nothing about the clear outline of a doorway which could be made out on one of the walls adjacent to Domenica’s kitchen. It was only when Antonia had been invited into Domenica’s flat for drinks one evening shortly after her purchase of the flat that the subject had been brought up, and even then raised indirectly.

“You’re most fortunate,” Antonia had said, “to have an extra room. You really are.”

Domenica had affected surprise. “But I don’t have an extra room,” she said. “I have the number of rooms that I have – and always have had.”

Antonia had looked into the glass of wine that Domenica had poured her; the wine came barely half way up the side of the glass, but that, she thought, was another thing. “What I meant,” she said, “is that your flat, which one would have thought would be the mirror image of mine – being on the same landing – appears to have two more rooms than I do. That’s rather surprising, would you not agree?”

Domenica would not. She knew exactly what Antonia meant – she was suggesting that the owners of Domenica’s flat had at some point stolen a room from next door. What a ridiculous thought! “No,” she said. “Not really. Many flats in this part of town are of different sizes. Some flats were intended for people of greater means than other flats. Some flats had maids’ bedrooms, for example.”

Antonia looked out of the window. She, or her predecessors in title to the flat, had lost a room, and she was in no doubt about where it had gone. It was, she thought, like one of those historic injustices that resonated down the centuries – a land grab of the sort that was imposed on the weak or the inattentive. This was exactly how Paraguay must feel about the loss of so much of its territory to its now larger neighbours. But, like Paraguay, there was not much she could do, and the conversation had turned to other matters.

Domenica remembered this conversation as she stood before Antonia’s door and prepared to press the bell. The two women had known one another for a long time, even before Antonia had moved to Edinburgh from Fife on the break-up of her marriage, but their relationship had not developed into the friendship which both had initially wished for. Now they had settled into a reasonably amicable, if slightly strained, modus vivendi in which each kept largely to herself but responded readily and in good grace to the duties of neighbourhood. Social invitations were extended and reciprocated, but they were carefully judged so as not to be too frequent as to lead to any form of imposition.

When Domenica had been on field work in the Malacca Straits, her flat had been looked after by Antonia. This had been a convenient arrangement for both of them, but on Domenica’s return she had made the shocking discovery that Antonia had removed a blue Spode teacup from her flat and was using it, quite openly, in her own. It was this teacup that now crossed her mind as she pressed Antonia’s bell.

When Antonia appeared at the door she did not seem to be at all surprised that it was Domenica who stood on her doorstep.

“Oh, it’s only you,” she said.

Domenica caught her breath. Only you… “You were expecting somebody more exciting?”

Antonia treated this as a joke. “Oh no! Well, maybe yes. But that’s not to imply that you’re not exciting… in your way.”

A short silence ensued. Declarations of war have come in more subtle forms than this, and Domenica would have been quite within her rights to interpret this as such, but then Antonia smiled and gestured for her to come inside, and Domenica decided that she would forgive the other woman’s tactlessness. There was no point in being at odds with one’s neighbour, whatever the provocation: selfishness in all its forms was what neighbours manifested and one simply had to accept it – unless one wanted distrust and downright enmity.

“Who were you expecting?” she asked. “I don’t want to get in the way, you know.”

This last remark was intended to imply that Antonia was the sort of woman to engage in trysts at ten-thirty in the morning, and that was exactly how it was interpreted.

Antonia smiled sweetly. “It’s a bit early for that,” she said. “Even for me.”

Domenica watched her neighbour. What exactly did that mean? That even if she were the sort to entertain a lover at eleven in the morning, ten-thirty would be slightly early?

“But let’s not stand in the hall forever,” Antonia continued, ushering Domenica into the living room. “As it happens, I’ve brewed some coffee already.”

And will it be served, Domenica asked herself, in my cup?

Antonia left to go into the kitchen. And it was then that Domenica noticed the smell. It was not an unpleasant smell, sweetish perhaps, slightly cloying, but certainly sufficiently pronounced to linger in the nose and on the palate; an olfactory memory without a link to substance. It was not the smell of coffee, Domenica thought. Definitely not.

After their walk on the path that led along the top of Cottesloe Beach, Matthew and Elspeth had returned to the hotel and sunk into a deep jet-lagged sleep that lasted for over two hours. When they awoke, it was almost six in the evening, and the fiery Western Australian sun had been drained from the evening sky, leaving it a strange, washed-out colour, almost a soft mauve.

What awoke them was not the change in the light, but the sound of a flock of parrots returning to one of the trees that towered over the hotel’s back garden. It was a sharp chattering, an excited flurry of sound that seemed to fill the air completely, echoing off the walls of the hotel courtyard in a profusion of high-pitched squeaks. “Our little friends,” said Matthew, raising himself on an elbow to peer out of the window at the small green birds. “Hundreds and hundreds of them.”

He shook his head and let it flop back onto the pillow. The air was still warm, and a light film of perspiration was making him feel sticky. He would shower, he thought, or have a swim.

“If you want a swim,” said Elspeth drowsily, “then remember to shower before you get in. In this hot weather…”

“I know that,” said Matthew. Did she think that he would jump into the water all sticky with sweat? He felt slightly irritated by her remark; he was not one of those children of hers, and he did not need to be told what to do. But then he thought: she must be used to telling people to wash their hands, to do this and that; teachers couldn’t help themselves, but it would pass now that she had stopped being a teacher.

And then he thought: what will that funny little boy be doing now? Bertie. With that dreadful mother of his and that ineffective father, Stuart. Why did Stuart not face up to that woman and tell her to leave Bertie alone? Of course, he would be scared of her, Matthew decided, as some men are terrified of their wives, and wives of their husbands.
