He checked the name and number on the display screen and saw it was Dr Kirtle, the pathologist. ‘Georgiou,’ he said.‘I’ve got the results of the tests on the body of Han Sun,’ said Dr Kirtle. ‘There’s something different from the previous two murders.’‘Oh?’‘Traces of a tranquilizer,’ said Dr Kirtle.‘What sort of tranquilizer?’ asked Georgiou.‘Do you want the full chemical name, or just where it’s normally used?’ asked Kirtle.‘The easy-to-understand one,’ said Georgiou.‘It’s the sort used by vets to knock out animals,’ said Dr Kirtle. ‘I’ll be e-mailing my full report over to you shortly, but I thought you’d want to know as soon as possible.’‘Yes, I do,’ said Georgiou. ‘Thanks.’He hung up and told Conway what Dr Kirtle had just told him.‘A vet connection?’ hazarded Conway. ‘Maybe,’ said Georgiou. ‘We’ll start checking vets and their supplies later.’His mobile rang again.‘We’ll never get to Vera’s at this rate,’ he grunted.This time the number on the screen was that of Dan Murphy, the news editor of the Cumberland News.
