The midnight knock

The knock came just after midnight. Three blows, a pause, then one more. Priya sat up without switching on the lamp. Her mother was working the night shift, and nobody they knew would visit at this hour. From the landing she could see the strip of frosted glass beside the front door. A shape blocked the streetlight. She waited for a voice, but heard only rain touching the letterbox. On the kitchen counter downstairs, her phone was charging. She wished she had brought it to bed.

She had checked the lock at ten. She remembered doing it because the key had stuck and she had needed both hands to turn it. Afterwards she had put a chair beneath the dripping kitchen window and folded a towel over the seat. These were ordinary things, completed in an ordinary order. Remembering them now made the house seem less familiar. The knock returned, softer this time. Priya moved down one stair and stopped where the banister would hide her from the glass.

‘It's about your mother.’ The voice was muffled by the door. Priya could not tell whether it belonged to a man or a woman. She imagined the hospital corridor she had walked along once, the vending machine with its flickering light, the people who spoke quietly near the lifts. She went down the remaining stairs too quickly and caught her foot on the mat. ‘What about her?’ she called. The shape shifted. Something pale rose beside the glass, close enough to catch the light.

It was a card. Priya leaned forward until she could read the name through the clear panel above the handle. Mrs Dobson, from the flat upstairs. The voice came again, clearer now: ‘She's trying to ring you. The main road's flooded. She can't get back yet.’ Priya looked towards the kitchen. Her phone lay face down beside the socket. The charging lead had slipped out of the wall. She opened the door on its chain, then released it when she saw the familiar blue coat.

Mrs Dobson stood in the hallway while Priya called her mother. Water dripped from the end of her umbrella onto the mat. Her mother sounded tired and annoyed with the buses, and the ordinary irritation was so reassuring that Priya almost laughed. After the call, she put the kettle on. Mrs Dobson asked whether she should have shouted through the letterbox sooner. Priya said she probably would not have heard. She fetched the towel from the kitchen chair and spread it beneath the umbrella. Then she switched on the hall light.
