person?â
âItâs possible. The bullets used have been retrieved and theyâll be tested shortly. If they match . . . well, then it becomes a different matter. Iâve told Billy Iâd be happy to look at a photograph of Gibson, if he can get hold of one. Perhaps itâll ring a bell.â
They stood in silence. Then Helen spoke.
âAnd youâre sure youâve never met him?â She was still having difficulty believing what she had just heard.
âAs sure as I can be.â Madden shrugged. âI havenât the faintest recollection of an Oswald Gibson. The only Gibson I knew was a boy at school called Henry. He was our cricket teamâs leg-spinner.â
Helen regarded her husband fondly. Maddenâs memory was legendary.
âYou can remember that Henry was a leg-spinner, but you donât remember Oswald at all. Itâs obvious thereâs been a mistake. I donât believe you ever met.â
âNeither do I.â Madden looked at her. âBut if I canât remember his name, how is it that he knows mine?â

âH AVE YOU FIXED AN appointment?â Madden asked. âIs Gibsonâs brother expecting us?â
âAny time this morning, he said. Heâs got some photographs to show you.â
Billy had been waiting at Waterloo station to greet Madden when his train pulled in.
âHe offered to send them to the Yard, but I thought it would be quicker if we did it this way. Besides, you might have some questions for him.â
There was no need for him to explain the need for urgency that lay behind his decision, least of all to the man who had taught him his trade, or the better part of it, as Billy liked to say. As an old investigator himself, Madden knew how important it was to resolve murder cases quickly â how trails tended to go cold after a few days â and the shooting of Oswald Gibson had now taken on a critical importance, thanks to the news Madden had received from Billy the evening before.
âIt didnât take the lab boys long. The slugs were in good shape, better than they expected.â
The call had come half an hour after Madden had got back from the farm. Billy had stayed late at the Yard waiting for the results of the ballistics examination of the two bullets.
âThe reason for that was that both had iron cores.â
âSay that again.â Madden wondered if heâd misheard.
âWell, bullets are made of lead usually. But these had iron cores coated in lead, which was why they kept their shape so well. According to the lab technicians, they must have been made in Germany during the last war.â
âIn Germany ?â
âApparently the Jerries started producing them when they ran short of lead. Iâm trying to get more on that.â
Madden absorbed the information in silence.
âBut thereâs no doubt about your labâs findings?â he asked finally.
âNone at all. The bullets were fired from the same pistol.â
âTimeâs become an important factor now,â Madden had explained to Helen later, when he told her he had decided to go up to London the following day. âThe murder in Scotland happened a month ago, and the police still have no lead in either case. Iâve no idea whether Gibson mentioning my name in that letter is significant or not. But thereâs just a chance that if I can remember him â his face, at any rate â it might give the police a starting point for their investigation.â
Greeting Madden on the platform now, Billy told him he had a police car outside that would take them up to St Pancras, where Edward Gibsonâs office was located.
âHeâs as keen as we are to get this question cleared up. Then Iâm going to have to go down to Lewes again to talk to Vic Chivers. Itâs odds-on this will become a Yard case now, with the Sussex police taking the lead, at least for the present. But
