"We don't want imagination in this matter, Mr. Rodgers. Facts sir."
Rodgers got up and put on his hat. "Well, we'll not be able to agree, I can see that," said he, "and as the case is in my hands, I am going away to look after evidence."
"Why not arrest Mr. Ainsleigh?"
"Because the evidence against him is not sufficiently strong," the detective sat down again. "See here Mr. Superintendent, if I so chose I could manufacture a case against three of these people at least, and give it to them pretty strong too. Supposing, for the sake of theorising mind, we say Mr. Ainsleigh killed the woman--"
"Which I am inclined to think he did, on the tie's evidence."
"Very good, I can show you how strong you can make the case against him, Mr. Young. This young man was at the ball, he hated the deceased and she hated him on account of the difficulty of the marriage with Miss Rayner. Ainsleigh wants money badly, and might have killed the old woman to get the fan and sell it for five thousand pounds. Also by marrying Miss Rayner who will inherit Miss Wharf's money, he gets rid of a mortgage that's troubling him. What was easier for him, than to pretend to put the silk scarf in his coat pocket, so as to blind those who saw him do it, and then to lure Miss Wharf out on to those steps and scrag her. Then he could pass the fan to Tung-yu who wanted it, and arrange about the money being paid. After that and when Tung-yu had gone off to the yacht, Mr. Ainsleigh could slip back into the ball-room and assist in finding the body. And remember, he says, he was strolling on the beach smoking, between the hours of eleven and twelve, and won't prove an alibi, though between ourselves I think he can through Major Tidman."
"Well," said Young dryly, "doesn't this go to prove his guilt."
"I can prove Tung-yu's in the same way," said Rodger's coolly, "he was in the cloak-room when Mr. Ainsleigh placed the scarf in the coat. He could easily have stolen it, as these Chinamen are clever thieves, and have then lured Miss Wharf on to the steps under the pretence of treating about the fan. Suddenly he slips the scarf round her throat before she can cry out, goes down the steps and on to the beach where a boat is waiting for him, and by now, may be on his way to his employer the Mandarin Lo-Keong."
"It sounds feasible I admit, but--"
"One moment," went on Rodgers eagerly, "quite as strong a case can be made out against Major Tidman. He did not come to the ball, but lurked in his room all the evening. Yet he came down to see Tang-yu--what about?--to sell the fan of course--"
