Fifteen minutes. That was if the traffic was good. Could be twenty. Leah looked at her phone again, checked the time, flicked open the Uber app. Still showing five minutes away which, based on the last ten minutes, was a lie. Say it was five minutes that meant a minimum of twenty until they could get to Aps. She thought about ringing the driver. April and Cora were over by the window, pulling back the curtain to keep an eye on the street. A black Tesla pulled up outside. The five minutes wasn’t a lie. The latest five minutes at least.

None of them really spoke in the car and the driver had taken this as his cue to turn his radio up, some rock station that April vaguely recognised as something she’d tried when 6 Music had been decommissioned. Some song none of them knew pushed them out onto the pavement outside the police station; a blast of pounding noise and someone singing about gambling. As the Uber door shut behind them and they were left with just the traffic noise on the street, a muffled don’t forget the joker shouted from the radio in the car behind them, Leah realised she had no idea what they were supposed to do.

In the moments after Aps had called it had all been clear. Our friend is in trouble: we go and help her. Nothing to contemplate, nothing to consider, no doubt. How do we get from here to her? The problem was as simple as that but now that problem had been solved, what now? None of them had dealt with this before. Leah was uncomfortably aware that the others were looking to her to guide them. What? Just because she called me? She wondered at that: why had she called me? But now wasn’t really the time. Leah led them inside, through a revolving door. If it wasn’t for the sign announcing The Bridewell Police Station it could have been any other office block, glass panelled walls demarcated into rectangles by red, steel strips. Beyond the initial door there was a decompression zone that was pretty common in large buildings, an expanse of space ended by a series of health screen machines that you had to proceed through to be allowed access further inside. Standard temperature check and cross reference to the national viral health register.

Leah cleared the health screens last. She should have expected it; her EU registered status always took longer to clear now in the UK, there were just more cross references back to the Italian database where her main health records sat. April and Cora were already at the enquiry window as she caught up.

“…we just want to make sure she’s okay,” Cora was saying to a dead pan police woman. She was ensconced behind a screen, mainly some sort of frosted glass that you couldn’t see through but with a clear window through which her head was visible. They were speaking through an intercom. She looked bored.

“What are they saying? Can we see her?” said Leah.

“No, you can’t see her,” replied the police woman, Inspector Martin from her name badge. “She’s still being processed under the terms of her arrest.”

“Can you at least tell us what she’s been arrested for?” said April. “It must be some kind of mistake.”

There was just a shake of a head in response and a gesture that they should all move to sit in the waiting area, a stretch of moulded plastic chairs bolted to the floor. There was a vending machine but most of the numbers displayed against its range of drinks had been scratched out. The three of them sat down. April got up again, walked up to the machine and looked at it.

“Anyone for a hot drink lottery?” she said. The others shook their heads. She swiped her contactless card and punched three numbers: two, two, three. Nothing. She tried again: one, one, two. This time the machine stirred, dropping a cup and filling it with a squirt of some unidentifiable black liquid topped off with hot water. It passed as black coffee and April cradled it back to join Cora and Leah.

“What do we do now?” said Cora.

“We wait, I guess,” said Leah.

“But we can’t do anything.”

“But we came. I think that’s all we could do,” said April. “We’ll be here when she gets released.”

“If she gets released,” said Cora.

“When,” said April. She blew across the top of her coffee and took a sip.

It was three hours before Aps was released, on a caution. In that time they discovered that 112 was definitely black coffee, 114 might have been a cappuccino, and 220 was the worst cup of tea that any of them had ever tasted. Talking about the drinks was the only thing that had distracted them from worrying about their friend. When she emerged, escorted by a woman dressed in blue scrubs, surgical mask hanging loose around her neck, she broke into a run and the four of us collided in the waiting area, Aps clinging to us in a desperate and grateful embrace.

“I lost my MedLet,” she said, repeatedly, as we held her. “I left it at James’s.”

None of them asked the questions they wanted to ask about that. They could all keep until later, for when it was safe to laugh about the whole thing, and start the enquiry about last night. They all bit their tongues about whether there had been any biting of tongues.

“What now?” said Cora. “Can we go?”

“Yes, it’s all sorted, I’m free to go.” Aps held up her wrist to show them a new MedLet, issued in the station, its warning light softly glowing green.

“Green equals clean,” said Leah.

“Green equals clean,” they all repeated.
