"Not that it is the slightest use telling them anything of the kind," Field muttered. "Whenever there is a mystery the press always gives us the credit for the possession of a clue. In that way they very often succeed in scaring our game away altogether. I don't say that the papers are useless to us, but they do more harm than good." All the same, Field was not quite at a loss to know what to do. Beatrice had given him a full and accurate description of the two adventurers who had vanished, leaving no trace behind them. They had suggested that all their belongings were at the _European Hotel_, but a question or two asked there had proved that such was not the case. "And yet they have gone and covered up their tracks behind them," Field said. "Why? Miss Darryll--I should say, Mrs. Richford--is quite sure that she did not alarm either of them. Then why did they disappear like this? Perhaps they were spotted by somebody else over another matter. Perhaps the gentleman who so scared our 'General' in the drawing-room of this hotel had something to do with the matter. We shan't get much further on the track of this interesting pair until I have had a talk with some of the foreign detectives." "You can, at any rate, look after the missing hotel servants," Mark suggested. But that was already being done, as Field proceeded to explain. It was just possible that they had been the victims of foul play. Most of the newspaper men had been cleared out by this time, and there being nothing further to learn, the hotel resumed its normal condition. People came and went as they usually do in such huge concerns; the mystery was discussed fitfully, but the many visitors had their own business to attend to, so that they did not heed the half score of quiet and sternfaced men who were searching the hotel everywhere. At the end of an hour there was no kind of trace of anything that would lead to the whereabouts of the missing men. Colonel Berrington came to the head of the grand stairway presently holding a little round object in his hand. "I have found this," he said. "It is a button with the initials R. P. H. on it, evidently a button from the uniform of one of the servants. As there is a scrap of cloth attached to it, the button has evidently been wrenched off, which points to a struggle having taken place. Don't you feel inclined to agree with me, Inspector?" On the whole Inspector Field was inclined to agree. Would Colonel Berrington be so good as to take him to the exact spot where the button was found? The button had been discovered on the first landing, and had lodged on the edge of the parquet flooring on the red carpet. They were very thick carpets, as befitted the character of the hotel. Inspector Field bent down and fumbled on the floor. He had touched a patch of something wet. When he rose his fingers were red as if the dye had come out of the carpet.
