together in the cramped living room of Leeming's house. He listened attentively to the recitation of events that had taken place in France, only interrupting when a certain name was mentioned.
'Brendan Mulryne?'
'Yes, Victor.'
'There was no reference to him in the newspapers.'
'Mr Tallis made sure of that,' said Colbeck. 'He refused to give any public acknowledgement to Brendan because he felt that it would demean us if we admitted any reliance on people like him. As it happens, I would have kept his name secret for another reason.'
'What's that, Inspector?'
'I may want to employ him again. If his name and description are plastered all over the newspapers, it would make that difficult. He needs to be kept anonymous.'
'I'm not sure that I'd have used him at all,' admitted Leeming.
'That's why I didn't discuss the matter with you.'
'I like Mulryne – he's good company – but I'd never trust him with anything important. He's likely to go off the rails.'
Colbeck smiled. 'In this case,' he pointed out, 'he did the exact opposite. Instead of going off the rails, he kept Mr Brassey on them. Largely because of what Brendan did, the railway can still be built.'
'Then I congratulate him.'
'You have a reason to thank him as well, Victor.'
'Do I?'
'One of the men who gave you the beating was Pierce Shannon.'
'I'm not surprised to hear it. He was a sly character.'
'Brendan laid him out cold on your behalf.'
'I wish I'd been there to do it myself,' said Leeming, grimly.
'The other man who attacked you was Liam Kilfoyle.'
'Liam? And I thought he was a friend of mine!'
'Not any more,' said Colbeck. 'I had the pleasure of exchanging a few blows with Mr Kilfoyle. I let him know what I felt about people who assaulted my sergeant.'
'Thank you, sir.'
Colbeck told him about the capture of the villains and how they had been handed over to the French police the next day. Thomas Brassey and Aubrey Filton had been overwhelmed with gratitude. The second visit to France had been eventful. Colbeck felt satisfied.
'So that part of the investigation is now concluded,' he said.
'What comes next?'
'The small matter of tracking down the killer.'
'Do you have any clues, Inspector?'
'Yes, Victor. One of them came from the most unexpected source, but that's often the way with police work. And I'm a great believer in serendipity.'
Leeming was honest. 'So would I be, if I knew what it meant.'
'Picking up a good thing where you find it.'
'Ah, I see. A bit like beachcombing.'
'Not really,' said Colbeck. 'Beachcombing implies that you deliberately go in search of something. Serendipity depends entirely on chance. You might not even be looking for a particular clue until you stumble upon it in the most unlikely place.'
'Serendipity. I'll remember that word. It will impress Estelle.'
'How is your wife?'
'She's been a tower of strength, sir.'
'Happy to have you at home so much, I should imagine.'
'Yes and no,' said Leeming, sucking in air through his teeth. 'Estelle is happy to have me here but not when I'm convalescing. She'd like more of a husband and a bit less of a patient.'
'You seem to be recovering well.'
Leeming's facial scars had almost disappeared now and the heavy bruising on his body had also faded. What remained were the cracked ribs that occasionally reminded him that they were there by causing a spasm of pain. He refused to give in to his injuries.
'I'm as fit as a fiddle, sir,' he said, cheerily. 'But for the doctor, I'd be back at work right now.'
'Doctors usually know best.'
'It's so boring and wasteful, sitting at home here.'
'Do you get out at all?'
'Every day, Inspector. I have a long walk and I sometimes take the children to the park. I can get about quite easily.'
'That's good news. We look forward to having you back.'
'I can't wait,' said Leeming. 'Much as I love Estelle and the children, I do hate being unemployed. It feels wrong somehow. I'm not a man who can rest, sir. I like action.'
'You had rather too much of it in France.'
'I like to think that I helped.'
'You did, Victor,' said Colbeck. 'You did indeed.'
'Mind you, I couldn't make a living as a navvy. A week of that kind of work would have finished me off. They earn their money.'
'Unfortunately, some of them tried to earn it by other means.'
'Yes,' said the other with feeling. 'Shannon and his friends were too greedy. They wanted more than Mr Brassey could ever pay them. Pierce Shannon always had an ambitious streak. It's a pity you got so little out of him when you questioned him.'
'That's not true.'
'He couldn't even tell you the name of the man who paid him.'
'Oh, I think that he gave us a lot more information than he realised,' said Colbeck. 'To begin with, we now know how he and his paymaster first met.'
'In a police cell.'
'What does that tell you?'
'Nothing that I couldn't have guessed about Shannon, sir. He got involved in a brawl and was arrested for disturbing the peace. Men like that always get into trouble when they've had a few drinks.' He cleared his throat. 'I'm bound to point out that the same thing happened to Brendan Mulryne after he'd left the police force.'
'He might not be the only policeman that we lost.'
'I don't think that Shannon was ever in uniform, sir.'
'What about the man who employed him?'
'We know nothing whatsoever about the fellow.'
'Yes, we do,' said Colbeck. 'We know that he's able to talk to someone in a police cell, which means that he's either a lawyer, a policeman or someone who used to be involved in law enforcement. I'd hazard a guess that he has friends in the police force, or he'd not have been given such easy access to a prisoner. Also, of course, we do have his Christian name.'
'Luke.'
'You can find out the rest when you get there.'
'Where?'
'To the station where Pierce Shannon was detained.'
Leeming was taken aback. 'You want me to do that, sir?'
'You enjoy a long walk, don't you?'
'Yes.'
'And you're chafing at the bit while you're sitting here.'
'I am, Inspector – that's the plain truth.'
'Then you can return to light duties immediately.' His grin was conspiratorial. 'Provided that you don't mention
