It was late by the time Rob and Sarah arrived back at the house with Maria. She’d stayed at the hospital for twenty four hours, reluctantly agreeing that she might need the rest but impatient to be away from the array of medical equipment and drugs and professionals that could do nothing for her. She’d joked with the nurses that she was like a diabetic with a sweet tooth in a candy store. You got nothing I can have but I want it all. Sarah had insisted on organising a taxi, worried about the hustle and bustle of the tube on Saturday evening. Maria had agreed on condition that she paid, they use a black cab, and that they make the driver cross the Thames via Tower Bridge. She told Sarah that it’d be another landmark she could sketch for her game, another little source of dopamine for people playing, another marker to help them navigate. Sarah thought there was more of the tourist in Maria than she cared to admit and that she probably just wanted to see the strange castle on the river.
They crossed the Thames as the sun was going down, its towers short and squat against the skyline in comparison to the jagged thrust of the Shard which dominated the view to the west. London was a city of silhouettes in the dusk, the fading light leaving just familiar shapes, the impression of places. Rob pointed out the sights as they appeared, sometimes just a momentary glimpse between office blocks and flats, and then a broader sweep of buildings as they crossed the bridge. A jumble of shapes and styles from the past and from the future. St Paul’s. The Gherkin. The Tower of London. City Hall. Traffic was unusually light and they didn’t get stuck in their crossing. Rob had hoped that perhaps they would so Maria would have more time to admire the view but she had to absorb it in less than a minute before they plunged into Whitechapel and everything closed in around them again.
When they stopped outside their house it was dark. The streetlight hadn’t been fixed and all of the lights inside were off. Rob let them in and called for Alex. There was no reply but it was then that they heard the shouts from outside.
Alex hadn’t gone back to the hospital. The others knew he blamed himself for what had happened but didn’t realise how hard it had hit him. He’d said he wanted a bit of time on his own and they’d respected that. In the time they’d lived together it was something they’d gotten used to. Rob teased him for being grumpy and they knew he’d never really settled into corporate life but neither of them thought there was more to it than that. If he was honest with himself he knew that the way he felt had a name. Depression. He should have been more clinical about it, more scientific, but he found it hard to apply his usual, objective mode of thinking to his own internal emotional landscape. He knew it had been getting worse and could trace some of it to the small sets of decisions that had taken him further and further from the things that he’d thought of as making up who he was. He remembered the genuine disappointment that Prof Miller had expressed when he’d told him that he was giving it up. He hadn’t been angry and he’d even understood it – noone’s getting rich mapping the universe – but there was almost a resignation to it. A sense that another bright talent was about to be eclipsed by the need to make the rent. There had been occasional rational moments when he realised that he could just jack it all in, walk away from the office and start again. Lately those moments had come less often. The sane and reasonable voice in his head drowned out by a choir of anxiety and regret and sadness.
Seeing Maria in the hospital had shattered what was left of the fragile peace in his head. It wasn’t just the guilt, on some level he knew that it wasn’t his fault, but the stark confrontation with mortality that had shaken him. There seemed to him to be a pointlessness to it. He’d always valued order and structure, causality and consequences, and whilst he could understand the facts of her disease he couldn’t explain why it was happening anymore than he could explain his own illness.
He put on his suit, straightened his tie, and headed up to the terrace.
Up on the roof Alex had his back to them. There was a small wall that ran round the sides of the terrace at knee height, there as a gentle reminder if someone got too close to the edge. You could perch on it and dangle your legs over the side of the house if you didn’t mind the guttering. None of them had ever thought of it as particularly dangerous. Early on the landlord had offered to put up a taller set of railings but they thought it would obstruct the view and had told him not to bother. Alex was standing on the wall, seemingly oblivious to the shouts from people in the flats in the adjacent street telling him to get down.
“What are you doing, Alex ?” Rob spoke quietly, holding his arms out, palms down, trying to signal a sense of calm that he didn’t feel to Sarah and Maria.
“Alex, please,” said Sarah. “Just step down and let’s talk.”
Alex didn’t reply and didn’t move. It had been a cloudless day and the temperature was dropping now that the sun had gone, the air was still. Alex didn’t feel the cold through his suit. Pure wool. He vaguely remembered that fact had been important at work, they’d all been given pointers on personal presentation in the first year on the graduate scheme. A couple of the partners, knowing his background, had joked that he’d have to leave the cords and the elbow patches behind now that he was a professional. There’d been no malice in it. He hadn’t been offended. It wasn’t until later that he’d begun to reflect on his decision and wonder whether he’d got it badly wrong. It was Maria that broke the impasse.
“Where are you Alex ?” He didn’t turn but this time he did reply.
“I don’t know. I honestly don’t know.”
“Latitude. Start with that. Tell me our latitude,” nudged Maria.
“I don’t know,” said Alex. “How would I know that ?”
“We’re not so far from Greenwich. I bet it’s roughly 51 degrees north and a touch over zero degrees west. How would you know if I hadn’t told you ? You taught me this Alex.”
“A fixed reference point. You need a fixed reference point and then you can work it out.”
Across Islington the lights went out. Later it was reported as a power cut, some problem with a sudden surge on the National Grid causing fail safes to kick in and the electricity to switch off. Around them the shining rectangular frames, the windows of the surrounding flats and houses, winked out. The streetlights snapped off. Shakespeare Street went dark. As their eyes adjusted to the absence of light Maria walked across the terrace, reached up, and took Alex’s hand.
“Tell me what you see,” she said.
“You can never see much here,” he replied. “Usually just Venus and some of the brighter stars. The moon obviously, when it’s out.”
Rob and Sarah cautiously crossed the terrace and stood on Alex’s other side from Maria. Sarah took his other hand.
“I saw Mars at the planetarium,” said Maria. “It’s the last thing I remember before I fainted. Where would it be if we could see it now ?”
Alex described its position relative to Venus and slowly began to tell them what he could remember about the positions of the distant objects they could see and the ones that they couldn’t. He was a little rusty but none of them would have known if he got anything wrong. He showed them Orion’s Belt, the three stars in a line that they could usually see above them, bright enough without London being dimmed, and then he noticed that the slightly skewed rectangle of Ursa Major. It was just visible now that the glare from the ground had been subdued and, just a slight turn of the head on from that, if he followed an imagined line from its two pointer stars, then he could make out Polaris. The North Star. He described it to the others.
“So you know where you are now,” said Maria squeezing his hand.
“It’s a start,” said Alex. “I could work out latitude but you know longitude is always trickier than that.”
“Because we’re always spinning, always moving,” said Maria.
“Yes. Yes, we are. I just wanted to make it stop.”
“You can’t make it stop Alex,” she answered. “Not like this. It’ll stop for you, sure, but everything else keeps on spinning. You’ve got your fixed point up there,” she gestured at the sky, “and maybe you just need to pick your own fixed point down here. Your own Greenwich.”
“I think I had it,” said Alex. “I think I used to have it. Maybe I just need to find my way back to it again.” He stepped down from the wall and quietly accepted Maria’s embrace. Rob and Sarah clutched at his back and the four of them stood on the roof holding him as he wept.
They stayed sat out on the terrace until the power came back on about an hour later. Sarah had made them all tea and they’d sat staring across the rooftops, hands wrapped round warm mugs, steam rising into the night air. When the lights returned the stars overhead faded but all of them swore they could still see the North Star, unwavering, the sky rotating around it.
