Death in the log streets Alex was woken up by an indignant Nadia Vole knocking at his door. He had overslept. “ This morning it is your last opportunity to experience the Stormbreaker,” she said . “Right,” Alex said. “This afternoon we begin to send the computers out to schools. Herr Sayle suggested that you take the afternoon for leisure. A walk perhaps into Port Tallon? There is a footpath that goes through the fields and then by the sea. You will do that, yes?” “Yes, I’d like that.” “Good. And now I leave you to put on some clothing. I will come back for you in… zehn minute.” Alex splashed cold water on his face before getting dressed. It had been four o’clock by the time he had got back to his room and he was still tired. His night expedition hadn’t been quite the success he’d hoped, he had seen so much- the submarine, the silver boxes, the death of the quard who had dared to drop one- and yet in the end he still hadn’t learned anything. Was Yassen Gregorovich working for Herod Sayle? He had no proof that Sayle knew he was here. And what about the boxes? They could have contained packed lunches for the staff of Sayle enterprises for all he knew. Except that you didn’t kill a man for dropping a packed lunch. Today was 31st March. As Vole had said, the computers were on their way out. There was only one day to go until the ceremony at the Science Museum. But Alex had nothing to report and the one piece of information that he had sent- Ian Rider’s diagram- had also drawn a blank. There had been a reply waiting for him on the bottom screen of his Nintendo when he turned it on before going to bed, Unable to recognize diagram or letters/numbers. Possible map reference but unable to source map. Please transmit further observation.
