Ian looked over at DS Bright and nodded in acknowledgement that this was to be his job. âBut, Jane, could you remove that chip from his back?â he continued. âYes, I suppose I could. I put it in so Iâd know roughly where to look for it. I could remove it from the same general area of a sheep or a horse so, given a patient who would accept an anaesthetic, I could take it out of a person. I would be breaking the law but I could do it.â âThen weâd better include all vets in the circular. Who else?â The two men watched Jane hopefully while she thought about it. She felt as if they were waiting for her to sing or to do a conjuring trick. âDentists, probably. ER nursing staff perhaps. If I think of any other profession, Iâll tell you.â âDo that. And weâll try to keep an eye on you for your safety, though I suppose youâll be the last person heâd allow near him carrying something sharp. How close would you have to get to tell whether an animal had been microchipped?â âReally close. Itâs not as though I landed him with the sort of transponder they attach to wildlife. This is only designed to give a number close up. I donât begin to get a reading until Iâm almost touching the animal. If you were thinking of a scanner that could pick up the presence of a microchipped person in a crowd â¦?â âI was.â âStandard equipment wouldnât do it. I brought my reader along to show you.â She opened the plastic box sheâd brought with her and put on Ianâs desk and drew out a neat instrument resembling an early mobile phone. âYou should go and talk to Mr Ilwand at the TV and computer shop. He designs that sort of gear. I seem to remember that there was a gadget on the market some years ago for detecting microwaves if they were escaping from a microwave oven and endangering the cook. It had to be taken off the market because it was too sensitive. He might be able to cobble together something like that for youââ Jane was interrupted by a knock and the entry of a young man in plain clothes and plastic gloves. He had once brought her a shorthaired pointer puppy for neutering. He turned out to be one of Ianâs constables. He delivered a paper bag to Ian, gave Jane a friendly nod and departed. âThis,â Ian said, âwill be a selection from the rubbish swept up and emptied from the waste bins at Kempfield last night. We were lacking any starting point whatever. It seemed to me that our culprit either did or did not visit Kempfield in an attempt to establish some sort of alibi. If not, then we start with the comparatively limited number of people of suitable physique who were not present. But you said that he had stuffed a handful of your duplicates into his pockets and he would have had to get rid of them. I really couldnât see him having a little private bonfire. And as long as he was walking around with his pockets full of your credit card slips he was marked. So I had my boys bag up the rubbish collected from Kempfield, separating out and discarding obvious irrelevancies like toffee papers. A couple of beat bobbies are looking in the townâs waste bins. Give me a moment for a glance at this little lot â¦â From his desk drawer he took similar gloves to those the constable had been wearing and drew them on. He sniffed the bag suspiciously and then tipped it out on to his unused blotter. âItâs a long shot. I donât suppose there will be anything,â he began, âbut when you start with nothingââ His voice broke off abruptly. There were more paper scraps than Jane would have expected. Ian took a ballpoint pen from his pocket and turned over two of them. âCredit card slips!â he said. âNo, donât touch them, they wonât have been fingerprinted yet, but take a look and tell me if you issued them.â Jane was
