There's a passage in a story by John Buchan where a minor character explains how a good mystery story is created: take at least three random subjects or events and connect them together. Here goes.
A toothbrush
Covent Garden
Wildflowers*
Interesting to let the mind float free and subjects appear unbidden, thought Marcus. The moon had risen and out at sea its reflections caressed the swelling waves. Calm the night after such a day of being about.
Gregory had phoned him, early. Marcus had been lying in bed. Sylvia had just returned from the bathroom and had folded herself into his arms. Their collective feet had conversed amicably as early morning feet do. She was still tingling a little from the passion they had shared, stretching herself languorously like a cat coming into the warm after a cold night out.
'Marcus,' said Gregory, 'it's today.' And that was all. The line went dead, but that was all he needed to know.
He extricated himself from Sylvia who was intent either on sleep or further love-making. She was incorrigible, but so so desirable.
I'll just take a toothbrush he thought as he swiftly shaved. He picked a new pink one still in its packet and put it in his bag with the papers, a map, his camera . . .
He thought about Ripley as he steered the car onto the motorway. That character fascinated him and he wondered if its inventor Patricia Highsmith had ever known such a man; a nice good-looking man, but selfish and nasty. Marcus wondered if he was selfish and nasty. He reckoned he was.
When he reached Covent Garden, parking illegally in Jermine street, he wasted no time in walking directly to Turino's. There, amongst the tourists and the out of town shoppers was Greg.
'I have this little package for you. Don't open it until you reach Southwold. Park in front of the Lion Hotel. Do nothing until she appears, which she will do after her lunch with the doctor. Then follow her. We think she'll go to Ben's. If she does we want the pictures . . . and as explicit as possible. Leave the package.'
It's at least two and a half hours to this village on the Suffolk coast. Until Ipswich he scarcely regarded the early summer colours, the plaintive skies, fields stretching to woods, the occasional grandeur of parkland.
He stopped for coffee at a services and called Sylvia.
'Hi Sylvia it's me.'
'Where are you? I was hoping we'd spend the morning together.'
'Well Greg called . . . I'm on my way to the seaside.'
'Oh . . . no time for Sylvia today?'
'Not today'
'Tonight?'
'if all goes to plan'
' You journalists, you're all the same . .'
But he wasn't. He was different. He didn't just write, he could investigate, uncover things, hack into mobile phones, get the compromising images.
Yes, she was going to Ben's . North, on the Norwich road. No hesitation. She drove fast. He had to have his wits about him. When she turned off the main road to the mill he carried on, then doubled back and two miles further on parked within sight of the building.
Her red car was there the courtyard. He decided on getting in from the garden so left the road for an adjoining field. Waist high in a profusion of grasses and wildflowers Marcus made his way painstakingly towards a collection of outbuildings, the indoor swimming pool, garages, an office.
The pictures were good. Both of them, together. The architect and the broker. Lovers, conspirators, thieves. They deserved everything coming to them.
He had entered the mill briefly. There were voices upstairs, a little laughter and then silence. He left the package on the kitchen table propped up against a vase.
They'd been following her movements for months after he'd taken his suspicions to Fred. Yes, he'd been so lucky. A wine bar conversation, an aggrieved employee, a few leaked documents and it all came together. And now this . . . the ****** stuff the paper loved.
He decided not to go back to Sylvia tonight but walk by the sea, let the gentle whoosh of water on the pebbled strand sooth his ruffled conscience. He had done his job. There would be other intrusions. Investigations, revelations. Mr Nice but nasty like The Talented Mr Ripley, he thought.
