“That
“Well, they did,” said Maggie. “The Polish bus driver went back to his wife. And some of his passengers tried to sue him.”
“I don’t think you should make any more love potions.”
“Oh, it wasn’t a love potion. It was something to make him sleep so he’d go back on days. Unfortunately it worked too well. He fell asleep at the wheel and went through the window of a lap-dancing club in Liverpool Street. Which is why I’m painting the room pink. Because I can’t get the bacon smoke off.” She raised the chain of her spectacles and squinted at him through polka-dot lenses.
Talking to Maggie was like using some kind of malfunctioning space communicator. Bryant decided to get to the point and keep it simple. “I know you’ve got a memory like a sieve, but I did ask you on the phone whether you knew anything about odd happenings in underground stations. I can be more specific now. Magnetism.”
Maggie peered over the top of her paint-spattered spectacles and frowned at him. “Oh, you know about that, do you?”
“No. That’s why I’m asking you.”
“No, I asked Yu.”
“Me?”
“No, Mrs Yu. I asked her to pop round. She’s in the garden.”
Maggie’s garden was a makeshift pet cemetery with a few desperate bluebells thrusting out of cracked paving stones. The goldfish had shuffled off its mortal coil in an earth-filled chimney pot, and even the budgie had embraced the light in a coal scuttle. Bryant looked out of the kitchen window and got a fright. For a moment he thought the moon had come out. Mrs Yu had a perfectly round white face and was peering in. She looked frozen.
“Sorry, love, I didn’t realise I’d locked you out,” said Maggie, opening the door.
“It’s bloody perishing in your yard,” said Mrs Yu. Although she was very Chinese in appearance, she had a strong cockney accent. “I was chatting to your dog.”
“Her dog’s dead,” said Bryant.
“Yes, he’s buried under the fishpond. Bolivar says he’s very happy, but he’s not so happy about being so near Happy.”
“I’m sorry?” said Bryant. Things were becoming confused again.
“Happy was my cat,” Maggie explained. “She’s buried near the dog, Bolivar. Mrs Yu knows a lot about atmospheric disturbances, so I invited her over. Plus, I wanted her to return my wok.”
Mrs Yu laughed a lot. She tittered at the end of every utterance. When she wasn’t laughing she was at least chuckling, and even when the chuckles faded she was still smiling. She plumped her big round frame down in the widest, most comfortable chair and elucidated. “So you want to know about magnetism. There was a story going around a few years ago about the tube. The guards started saying that the addition of extra metal floodgates throughout the system created some kind of supercharged atmospheric whirlpool. It was only supposed to happen when trains passed through the tunnels with great frequency, during rush hours. See, before that, electrical particles ionised the atmosphere and escaped upwards on the air currents. But the iron flood doors slowly became magnetized, creating differences in pressure that made passengers feel sick and dizzy.”
“I’m not sure I put much store in that,” said Maggie. “I mean, electrical whirlpools – it sounds a bit like those adverts for shower gel with ginseng extract to wake you up. You know, pseudo-science.”
“That’s good, coming from a woman who believes you can find water under the ground just by wandering about with a stick.”
“Dowsing is scientifically proven,” Maggie insisted. “I can always find water.”
“Of course you can,” said Bryant. “You’re a Londoner; it’s impossible to get away from the bloody stuff. So, no likelihood of someone becoming disoriented and passing out in the underground due to magnetic forces, then? Because I’ve heard there are powerful ley lines passing through King’s Cross.”
“That’s true,” said Mrs Yu, “but ley lines are just pathways between ancient sacred sites. There are other hidden powers at work under London. Wherever all four elements interact, you create conflict. King’s Cross is one of the very worst sites – ”
“What are you talking about?”
“The electric trains and power cables – fire. The underground rivers and pipelines – water. London clay – earth. The winds in the subway system – air. There are storms down there that disrupt the psychic atmosphere.”
“Meaning what exactly, you get headaches? You catch the wrong train? You start seeing dead people?”
Mrs Yu happily wagged a finger at him. “Ill humours are not such a crazy concept. The Victorians believed germs were transported through miasma – the air itself. That’s why they built Victoria Park in Mile End, as a barrier to protect the city’s rich property owners from working-class diseases. They thought the germs would float across to them on the breeze.”
“Yes, but they were wrong, weren’t they? John Snow discovered that cholera was water-borne. You think there’s such a thing as bad air?”
“Well, we know that electromagnetic disruption can actually make people ill, and the jury’s still out on radio masts, isn’t it? There’s still no proper air-conditioning in the London Underground system. Back when the trains were pulled by steam engines, the engineers tried everything to clear the air. They built ventilation shafts that came up behind fake house-fronts in Bayswater. Later, when the Victoria Line was built, a structure called the Tower of the Winds was constructed in a garden square up in Islington. It was meant to introduce cool breezes into the tunnels, but wasn’t much more successful.”
“I was just reading about plans to chill the subway system during heat waves by using water from the lost rivers,” Bryant interjected.
“Nothing ever works,” Mrs Yu said, tittering. “The air beneath King’s Cross remains old and stagnant. It’s polluted with all kinds of toxins, and its composition changes all the time.”
“Well, here’s my problem.” Bryant seated himself wearily and helped himself to a ginger biscuit. “My problem is – dear Lord, it sounds so absurd. How can I explain this? Some of our most successful prosecutions have been built around a tiny shred of evidence, a piece of broken glass, a boot print, an overheard phrase. This investigation hangs on a sticker, a travel card, a few odds and sods and a bad feeling. Nothing more. They’ll hang me out to dry if I get it wrong this time.”
“Then let me see if I can help,” said Mrs Yu.
Bryant set out his case. “A student died of tobacco poisoning in the underground. But even though – as you say – the air in the tube is bad, there’s been no smoking down there for years. My coroner says someone sprayed the lad with the stuff. According to his medical records, he suffered from asthmatic attacks. We didn’t find an inhaler on him, so I’m thinking that the killer substituted his inhaler for one containing poison, then took it away. But I also have to look into the possibility of accidental death. You don’t suppose certain toxins – heavier-than-air ones – could have sunk to the bottom of the system and poisoned him, do you? Through these whirlpool things? We tested the air and found nothing.”
“That’s hardly surprising,” said Mrs Yu. “Every time a train rushes past it displaces the air and transfers it to another magnetic collection point.”
“Surely it would be easier to accept your coroner’s theory about the spray?” asked Maggie. “I don’t know why you’re making life difficult for yourself.”
“It’s what I do,” said Bryant glumly. “If his death was an accident, then Gloria Taylor was also an accident, and suddenly there’s no case. Which would be wonderful, because it would mean no-one else is in danger. The alternative is to look for a clever, calculating killer who murders randomly, without remorse, and who leaves absolutely no trace.”
“Well, it seems to me that you’re caught between two worlds, Arthur – the one that lies beneath London, and the hidden world in which this person you seek moves and connects. For once, you must try to think like a civilian and not like a policeman. I think the investigation is testing your powers in new ways. The tube network isn’t the only ghost system in operation – there’s an entire world of invisible connections we never normally get to see. It’s just a matter of finding the key. Let’s consult the cards.”
She pulled a key from her crimson coiffure, unlocked a drawer in her kitchen table and brought out a packet of
