Half an hour later he found himself shown into a smartly furnished office where Mr. Gavin Ramsay sat at a handsome desk surrounded by shelves and cabinets whereon and wherein were set out the products of the brains of many inventors--models of machines, mechanical toys, labour-saving notions, things plainly useful, things obviously extravagant. The occupant of this museum glanced at Allerdyke and the box which he carried with an amused smile, and Allerdyke said to himself that Appleyard was right in his description--if the man was crippled and deformed he certainly possessed a beautiful face. "Mr. Marshall Allerdyke," said the hope of inventors, glancing at the card which his visitor had sent in. "The same, sir," replied Allerdyke, setting down his box. "Mr. Ramsay, I presume? I heard of you, Mr. Ramsay, through Wilmingtons, in the City; heard you can be of great use to inventors. I have here," he continued, opening the box, "a railway chair, invented by one of my workmen, a clever fellow. You see, it 'ud do away with the present system of putting wooden blocks in the chairs now used--this would fasten the sleepers and rails together automatically. It is patented--provisionally protected, anyhow--but my man's never got a railway company to try it, so far. Think you can do anything, Mr. Ramsay?" The hunchback got up from his desk, took the invention out of its box, and carefully inspected it, asking Allerdyke a few shrewd questions about the thing's possibilities which showed the caller that he knew what he was talking about. Then he sat down again and went into business details in a way which impressed Allerdyke--clearly this man, whoever he was, and whatever mystery might attach to him, was a smart individual. Also he had a frank, direct way of talking which gave his visitor a very good first opinion of him. "Very well, Mr. Allerdyke," he said, in conclusion. "Leave the thing with me, and I will see what I can do. As I say, the proper course will be to get it tried on one of the smaller railway lines--if it answers there, we can, perhaps, induce one of the bigger companies to take it up. I'll do my best." Allerdyke thanked him and rose. He had certainly done something for his man Gankrodgers, and he had seen Ramsay, or Rayner, at close quarters, but--Ramsay was speaking again. He had picked up Allerdyke's card, and glanced from it to its presenter, half shyly. "You're the cousin of the Mr. Allerdyke whose name's been in the papers so much in connection with this murder and robbery affair, I suppose?" he said. "I've seen your own name, of course, in the various accounts." "I am," replied Allerdyke. He had moved towards the door, but he turned and looked at his questioner. "You followed it, then?" he asked. "Yes," assented Ramsay. "Closely. A curiously intricate case." "Any solution of it present itself to your mind?" asked Allerdyke in his brusque, downright fashion. "Got any theory?"
