‘Questioning senior figures at the railway company,’ said Colbeck. ‘I left him to do that while I called at the home of William Ings.’
‘But the cupboard was bare.’
‘The man himself may not have been there, Superintendent, but I feel that I gathered some valuable clues. I strongly advise that we keep the house under surveillance in case Mr Ings should chance to return.’
‘Why should he do that?’
‘To give his wife money and to see his children.’
‘The complications of marriage!’ sighed Tallis, sitting back in his chair. ‘The more I see of holy matrimony, the more grateful I am that I never got embroiled in it myself. I daresay that you feel the same.’
‘Not exactly, sir.’
‘Then why have you remained single?’
‘It was not a conscious decision,’ explained Colbeck, unwilling to go into any detail about his private life. ‘I suppose the truth is that I have yet to meet the lady with whom I feel impelled to share my life, but I have every hope of doing so one day.’
‘Even if it might impede your career as a detective?’
‘Unlike you, sir, I don’t see marriage as an impediment.’
‘Anything that prevents a man from devoting himself to his work is a handicap,’ announced Tallis. ‘That’s why I limit my social life so strictly. We have an enormous amount to do, Inspector. London is a veritable sewer of crime. Our job is to sluice it regularly.’
‘I have a feeling that this case will take us much further afield than the capital, Superintendent,’ said Colbeck. ‘The robbery occurred in a rural location in Buckinghamshire and that county is hardly a hive of criminal activity. On the other hand, the crucial information about the mail train was doubtless supplied by someone in London.’
‘William Ings?’
‘I reserve judgement until we get conclusive proof.’
‘It sounds to me as if we already have it.’
‘The evidence is only circumstantial,’ Colbeck pointed out. ‘Do I have your permission to arrange for the house to be watched?’
‘No, Inspector.’
‘Why not, sir?’
‘Only a fool would dare to go back there again.’
‘Only a fool would run up gambling debts.’
‘I can’t spare the men.’
‘You said that I could have unlimited resources.’
‘Within reason,’ Tallis reminded him, ‘and I don’t happen to think that keeping this house under observation is a reasonable use of police time. Ings has obviously gone to ground somewhere else. I doubt if his wife will ever see the rogue again.’
Colbeck was far too used to having his suggestions blocked by his superior to be irritated. It was something he had learnt to accept. Edward Tallis seemed to take pleasure from frustrating any initiatives that the other man put forward. It was one of the reasons why the antipathy between them had deepened over the years.
‘It’s your decision, sir,’ said Colbeck with exaggerated civility.
‘Abide by it.’
‘What else can I do?’
‘Invent some hare-brained scheme of your own to subvert me,’ said Tallis with vehemence, ‘and I’ll not stand for that. It’s happened before, as I know to my cost.’
‘I only took what I felt were the appropriate steps.’
‘You resorted to untried, unauthorised methods. And, yes,’ he admitted, raising a hand, ‘they did achieve a measure of success, I grant you. But they also left me to face a reprimand from the Commissioners. Never again, Inspector — do you hear me?’
‘Loud and clear, sir.’
‘Good. You must follow procedure to the letter.’
‘Yes, Superintendent.’
‘So what’s your next step?’
‘To meet up with Victor Leeming and hear what he found out at the railway company. He acquitted himself well when he talked to the people who were on board the train. He asked all the right questions.’
‘I’ll want to know what he gleaned from the railway company.’
‘Of course, sir.’
‘What are your plans for tomorrow?’
‘I intend to catch the earliest possible train to Birmingham.’
‘Why?’ demanded Tallis.
‘Because I need to speak to the manager of the bank to which that money was being sent. He has a key to open that safe. I’d like to know how it came into the possession of the robbers.’
‘So you suspect treachery at that end as well?’
‘I’m certain of it, Superintendent,’ said Colbeck. ‘I believe that we’re looking at a much wider conspiracy than might at first appear. There was inside help at the Post Office, the bank and, possibly, at the Mint. The robbers might also have had a confederate inside the London and North Western Railway Company,’ he argued. ‘I don’t believe that William Ings is the only man implicated.’
Tallis grimaced. ‘In other words,’ he said, tartly, ‘this case will take a long time to solve.’
‘I’m afraid so.’
‘Then I’ll have to endure even more harassment from all sides.’
‘Your back is broad, sir.’
‘That’s the trouble,’ complained Tallis. ‘It presents a big target for anybody with a whip in his hand. If we fail to make swift progress in this investigation, I’ll be flayed alive. I’ve already had to fight off the so-called gentlemen of the press. Tomorrow’s headlines will not make pleasant reading, Inspector. My bad tooth is throbbing at the prospect.’
