"You are both rather difficult to deal with," remarked Steel, with a shrug. "However, I'll explain, and you can draw your own inferences. It seems from what Mrs. Benker said that Mr. Wilson was mostly out all night and in all day. Also he was frequently absent for a long time. He likewise took much interest in Society newspapers and in the movements of the aristocracy. He also wore on his chain an ornament--a red-enamelled cross, in fact." "What!" cried Giles, with a start, and he noted that the Princess started likewise, and that her face grew pale. "He wore a red-enamelled cross," repeated Steel imperturbably, "on his watch-chain. Mrs. Benker had been in the service of the late Lady Summersdale when the diamonds of that lady were stolen. She remembered that a red-enamelled cross had been found in the safe whence the jewels were taken. Wilson was amused at this. He said that the cross was the emblem of a charitable society from which he received a weekly sum. Well"--he hesitated and looked at his listeners--"that clue came to an end. I lost sight of Wilson. I then went to look for _The Red Cross_--the yacht, I mean!" "What has the yacht to do with Wilson?" asked Ware angrily. "If you remember, sir, I told you that Wilson was the man who served the summons on Mr. Morley, and who, as I believed, killed Miss Kent. He afterwards fled with Miss Denham and went on board the yacht. Is not that the case, sir?" "So far as I can judge, it is," muttered Giles reluctantly. "Well, then," went on Steel triumphantly, while the Princess--as Giles observed--listened intently, "I looked after that yacht. I could not find her, but I am looking for her now. That is why I am in the country. I came up this morning from Deal, and I go back there to-morrow. I find, sir, that this yacht puts in at various places every now and then." "Most yachts do." "Yes, sir. But while most yachts are at anchor in a place does a burglary invariably occur? No, sir, wait," for Giles had sprung to his feet. "Lady Summersdale's place was on the seashore. Her diamonds were stolen. At the time this yacht was at anchor in the bay. A red cross was found in the safe. The boat is called by that name. Several times I find that when the yacht has been at a certain place a burglary has occurred. This man Wilson wears a red cross on his watch-chain. Now, sir, I believe that he is one of a gang of burglars--that the cross is a sign. This explains his interest in the Society papers. He wants to find out where the best swag is to be found, and----" "But what has all this to do with my friend Anne?" cried the Princess. Steel shrugged his shoulders. "I say nothing," he replied. "You can draw your own inferences." "Do you mean to say that Miss Denham----" "I say nothing," interrupted Steel, catching up his hat. "Mr. Ware, I am at your service when you want me. Princess!" He bowed and went out.
