Rachel Sargeant - The Good Teacher - A gripping thriller from the Kindle top ten bestselling author of ‘The Perfect Neighbours’

He peers through the open passenger door. Well, there’s no one at it on the back seat. Hardly surprising. That shrieking radio would put anyone off. Reg lays his bike in the long grass. They must be in the ditch or the field beyond. You’ve got to admire their stamina. They’ve been down there longer than it’s taken him to ravish his Olympic Breakfast with extra mushrooms. With the stealth of a marine commando, he moves towards the ditch. Perhaps he’ll share this one with Doreen. It might put her in the mood for some how’s your fath—

“Father God in Heaven,” he gasps and stands stock-still, the taste of bile mounting in his mouth. His eyes fix on the glint of metal and the shiny patch of red seeping through the grass. In the next instant, stomach heaving, he’s back on his bike, tackling the rest of the hill from the saddle.

The milkman came at about 6.30 a.m. – at least she assumes it was 6.30 a.m. because that’s when he always comes. His chinking of bottles is often the first sound she hears on waking. This morning, frozen by the enormity of her situation, she didn’t think to call out to him until she heard the clanking, whirring sounds of his aged milk float dying away as it left. Hers is the only house in the street that still has milk delivered.

The final spin of the washing machine behind the closed kitchen door filled the silence after that. Then time became vast and empty until the whistling postman. The mail usually arrives before 8 a.m. despite changes at the Post Office, so that must make it about 9 a.m. now.

There’s a distant crunching outside. More steps follow and grow louder as they trip their way up the gravel. It must be Linda. Of course, it’s nine o’clock. Linda and Dean will have dropped the children off at school and then come to pick her up, as arranged. She pictures Linda teetering up the path, her broad feet forced into tiny sandals.

In the background a car engine rumbles. She’s amazed that she can hear it above her hammering heart. Dean will be waiting in the car. She hears a light tapping on the front door glass. Linda’s false fingernails. She forms the words “Linda, help” at the back of her mouth, trying to force them through the heavy adhesive that clamps her jaws together.

“Gaby, are you in there?” Linda’s voice invades the house through the opened letterbox. “Are you going to let me in?”

With all her might, she gulps out one more “Help”. The sound reverberates in her ears and, for a moment, she thinks it’s reached the front door. The letterbox snaps shut and footsteps move around the house towards the lounge window. She rocks against the chains, causing two of the chair legs to lift and then slam down with a muffled thud on the carpet.

“Dean, she must have forgotten.” Linda’s voice is directed away from the house. “I’ve put their milk in the bushes otherwise it’ll be honking in this heat.” Linda’s jerky steps return past the front door and recede down the path, the sound of gravel scattering in their wake.

Gaby struggles to catch her breath as a car door closes and the car speeds away. Tears prick her eyes. Her best hope of rescue will be joining the Penbury ring road without her. Crying makes her head throb, but she weeps on. The fight flowing out of her.

Reg – ice-numb now despite the heat – tries to lean his bike against the potting shed but it slips, clattering to the ground. The noise brings Doreen to the back door.

“Where the heck have you been all this time?” She squints at him. “You look peaky, a bit like your porridge looked before I chucked it. I suppose you want me to get you something else now?”

“Whisky,” Reg gasps.

What time is it now? Exhaustion giving way to panic again. How long can she survive without a drink? It’s been hours and her lips feel like crumbling plaster. Gaby makes another effort to calm down by breathing in through her nose and letting the air slowly reach her lungs. She clutches at any passing thought to occupy her aching mind. The letters on the doormat. She likes getting letters, even if most are mailshots. Her thoughts wander to the postman. She blinks back tears again, regretting that she’s never really looked at him before and wondering whether there’ll ever be another chance.

A car pulls up outside the gate. The engine stops and a door slams. Heavy shoes trudge along the gravel accompanied by faint crackling voices like a radio. She breathes in sharply, preparing to hum out as before, but this time ready for disappointment.

“Yes, sarge. If there’s no reply, we’ll force entry,” a calm voice says on the other side of the front door.

Gaby’s breathing quickens and she can hardly believe her ears. She’s in some other world, unable to move. Seized by terror, suddenly afraid to end her familiar incarceration after so many hours. But then her survival instinct takes hold and she presses against the chains, rocking back and forth, willing herself closer to the window. After hearing three sharp knocks at the door, she crashes to the carpet. Shattering pain spreads across the side of her face. Everything numbs and darkness comes.

I scramble up the metal staircase inside the south entrance to Penbury Police HQ. Late. Should have taken the car instead of waiting for the bus, but I was flustered enough without getting behind a hot, sticky steering wheel. I try taking the steps two at a time, but the thick woollen tights drag on my knees. Unseasonal legs, and slow, but ladder-free at least. I tried my best with my mother’s honey blush tights, but the minute I tore open the packet and the two bits of beige nylon flopped down, I knew they were designed for an underfed tenyearold. And that was before their accident.

I up my pace and clamp my shoulder bag to my side – my one act of rebellion against Mum’s restyling efforts.

“Now all you need is a briefcase,” she trilled at the end of our shopping session.

“But I have to be approachable, Mum – a friendly face serving the whole community.”

“Really, Pippa, darling, you sound like that rather grand lady officer they keep interviewing on the local news.”

I swelled with pride when Mum made that comparison. I haven’t met Superintendent Chattan yet, but I’ll settle for having half the poise the woman exudes in her television appearances.

At the top of the stairs I slow down, trying to get my breathing under control. My bag’s heavy, too much fodder inside. Pink lipstick from Mum, change for the bus home, tissues, sweets, apples, the Penbury CID Induction Pack and a small handmade card in joined-up writing: Good Luck, Sis. Love Jamie .

Rushing along the narrow corridor past the glass-panelled general office, I tell myself I’m not all that late, but I catch sight of four heads already barricaded behind high in-trays and jumbles of phone consoles and computer screens. I break into a trot and wonder which workstation mine will be. What if my new colleagues don’t rate me? Being late on day one isn’t the best way to win them over. They might not speak to me – I hate silences. Hopefully I’ll be out on the road most of the time.

I touch the buttons on my jacket. Too formal? Another idea of my mother’s. Now you don’t have to wear that ghastly uniform anymore . After trouble with toothpaste spatters, I had to change out of her pink lace blouse selection into a royal blue T-shirt, an old favourite. It looks good with the jacket – so long as I don’t undo the buttons to reveal its full glory. If the weather forecast is anything to go by, I’ll have to boil.

Through the chipped double doors, across the stairwell and into the corridor beyond, I reach a line of varnished wooden doors, each bearing a nameplate. I stop before the first one: Detective Inspector Liz Bagley . I re-check my jacket buttons.
