Lacey ignored him. Troy put his shoulder to the wood. It gave on the fourth heave. He moved the door into the hall and stepped back, keeping an eye on Lacey who was leaning against the stair rail, very still, his face expressionless.
Barnaby entered the studio, which seemed innocent enough. And meticulously tidy in comparison with the rest of the house. Some canvases were stacked against the wall, one or two tied together with string. The easel was covered with a cloth peaked into a square by the canvas beneath. The floor was swept clean and there was the scent of turps and resin in the air. A trestle table held an orderly array of jars and brushes and there was an unlit Calorgas heater in one corner.
In the hall Troy stood, legs apart, ready for anything. Over his head the electric meter buzzed like a trapped bee. He glanced up. Slim grey cables snaked about. Funny to see a meter in a private house. Plenty of council tenants had them of course. Set too high as often as not so there’d be some cash to spare when they were emptied. A bloody irritating noise. He turned and looked up. It wasn’t the meter buzzing. It was flies. Dozens of them; great filthy bluebottles with iridescent wings. They were clustered all over something. Something jammed behind the meter. He stood on his toes and stared harder.
‘Chief . . .’ Barnaby hurried out. ‘Look - up there!’
‘Get a chair - and something to hold it with.’
Troy climbed on to one of the dining chairs with a dirty tea towel in his hand and tugged at the knife. It bloomed with dark stains. The flies lifted sluggishly but didn’t go far. As Troy held it out they hovered over his hand. Barnaby looked at Michael Lacey, who moved away from the banisters and came towards them, staring at the knife in astonishment.
‘Can you explain what this is doing behind your meter, Mr Lacey?’
‘Of course I can’t.’
‘Does the knife belong to you?’
When Lacey remained silent Troy gave him a none too gentle nudge. ‘The chief inspector’s talking to you.’
‘I don’t know . . .’ He looked more closely, his mouth puckering with distaste. ‘Yes . . . it’s the knife we use for the vegetables.’
‘And where have you hidden the clothes, Mr Lacey?’
‘What?’
‘The dungarees, the cap, the gloves. The tights.’
‘Tights. What d’you take me for? A transvestite?’
‘The clothes that you wore,’ Barnaby continued implacably, ‘when you killed Mrs Rainbird.’
‘When I -’ Lacey gazed at him open mouthed. ‘You’re raving mad. You’re not hanging that on me. I’ve heard all about police corruption. You probably planted that yourself. Came round here earlier when I was out.’
Barnaby was turning back into the studio when Lacey ran for it. Pushing the chief inspector violently aside and hitting Troy in the chest, he flew through the doorway and raced across the open space in front of the cottage. Troy, picking himself up, ran after him and brought the man down by the car. When Barnaby reached them Lacey was handcuffed and Troy pink faced with exertion and pride.
‘In the car, Lacey.’
Barnaby’s prisoner stared at him. The look held everything he expected to see, fright and despair, but there was something else behind his eyes. A disturbing expression that the chief inspector could not put a name to. Troy bundled the man into the back seat. Barnaby put the knife into the boot, then said, ‘Do you have a key to secure the house?’
‘It’s never locked.’
They drove off. As Troy slowed down to approach the junction of Church Lane and the Street Katherine Lacey came round the corner with two of the dogs. There was just enough light for her to recognize Barnaby, and she half smiled. Then she saw her brother and her face changed. She called out, ‘Michael?’ and started to cross the road towards them. He lifted his handcuffed wrists and made a square around his face, shouting, ‘I’ve been framed!’ Then the car gathered speed and drove off.
Chapter Eight
It was dark when they reached the station. Michael Lacey received an intimation and was asked if he wished to make any telephone calls. He declined and started looking round him with some interest. He seemed to be recovering his savoir-faire fairly quickly. By the time Barnaby handed him over to the custody officer he was even exhibiting a certain amount of bravado. Barnaby heard him place a facetious order for toast, tea, a mixed grill, apple pie and ice cream. The chief inspector asked how the other prisoner was faring.
‘Sleeping like a baby, sir. And snoring her head off.’
Barnaby returned to the incident room where Troy was completing a house-search form. It was too dark to start looking for the murderer’s clothes, but at first light they’d get started. More action forms had come to roost on his desk next to his cold gluey Chinese takeaway. No need to read them all now. He’d got the murderer downstairs under lock and key. He stood by the window looking up at the indigo sky thickly patterned with bright stars, and wondered at his feelings of unease.
