‘Take a screenshot, will you, Maura?’ Sergeant Murphy asked the garda. Then, to Katie, ‘Watch.’

Orla went back into the house and the Jaguar continued to reverse out of the driveway, bumping over the kerb as it went, so it was clearly not being driven by somebody who cared for it, or who was used to taking it out of Justice Quinn’s driveway. It stopped for a few seconds in the road while the driver changed gear, and Sergeant Murphy said, ‘That’s it, freeze it there.’

Through the rear window of the Jaguar, it was just possible to see the silhouette of somebody sitting in the front passenger seat.

‘See the recorded time here?’ said Sergeant Murphy. ‘It was less than twenty-three minutes between the Jaguar being driven away from Tivoli Park to the moment when those two officers heard the first explosion up at White’s Cross. That means the passenger has to be Justice Quinn. It would have taken approximately fifteen minutes to drive from Tivoli Park to White’s Cross – maybe a few minutes longer depending on the traffic. Then a few minutes more to shift Justice Quinn into the driver’s seat, depending on his condition.’

Katie said, ‘He wouldn’t have gone voluntarily, that’s for sure, and there’s no way in the world that he would have let anybody else drive his precious car. Either he was threatened and he was under duress or else he was drugged and he was unconscious – or at the very least so doped-up that he was incapable of putting up any resistance.’

Sergeant Murphy nodded. ‘It’s not irrefutable proof, of course, but it all seems to fit, wouldn’t you say? It looks like Mrs Quinn and this unidentified fellow conspired together to kill him.’

Katie thought of Orla saying, ‘I should have divorced him, shouldn’t I, years ago? But I could never think of it, Katie. I couldn’t bear to think of us living apart. I loved him so much. I adored him.’

She sat looking at the silhouette of Garrett’s head in the passenger seat of his beloved Jaguar. Then she turned to Sergeant Murphy and said, ‘I only pray that he was gone before they set his car on fire.’

Katie and Robert and Detective Sergeant Begley went back down to Katie’s office.

‘So what’s the plan?’ asked Robert.

Katie turned to Detective Sergeant Begley. ‘Sean – you said you might have an inkling who that fellow is who planted the bomb in the pharmacy lab. If you give yourself some time, do you believe that it might come to you? Myself, I have a little leprechaun in my brain who’s sitting there smoking and reading the paper and if I’ve forgotten anything like somebody’s name I have only to ask him. Nine times out of ten he comes back after a while and gives me the answer.’
