"Oh, quite," Dr. Andrews replied. "One's experience tells that. Sir Charles was quite stiff and cold. I should say that he had been dead quite four hours when the door was broken down."

Just for an instant the doctor hesitated and his easy manner deserted him.

"I must see Sir Charles's regular medical man before I can be quite definite on that point," he said. "I have no doubt that death was caused by natural means, at least I see no reason at present to believe anything to the contrary. Indeed, if any doubt remains after that, there must be a _post mortem_, of course. But still I hope that such a course will not be necessary."

In a vague way Beatrice felt uneasy. If this gentleman was not actually concealing something, he was not quite so satisfied as he a.s.sumed to be.

"I should like to see my father, if I may," Beatrice said quietly.

The doctor led the way to the bedroom and closed the door softly behind the girl. His face was a little grave and anxious as he walked down the stairs.

"You appear to be a friend of the family," he said to Mark as he stood in the hall. "There are symptoms about the case which frankly I don't like. There was no occasion to lacerate Miss Darryll's feelings unduly, but I must see the family doctor at once. It is just possible that you may happen to know who he is."

Mark was in a position to supply the desired information, and Dr.

Andrews drove off, his face still very grave and thoughtful. Meanwhile Beatrice found herself alone with the dead body of her father. He was only partially undressed; he lay on the bed as if he had been overcome with a sudden illness or fatigue. The handsome boyish features were quite composed; there was a smile on the lips, and yet the expression on the face was one of pain. Sir Charles appeared to have died as he had lived--gay, careless, and easy to the last. Always neat, he had placed his studs and tie on the dressing-table; by them stood a little pile of letters which had evidently come by a recent post. They had been carefully cut open with a penknife, so that Beatrice could see they had been read.

There were tears in the girl's eyes now, for Beatrice recalled the time when Sir Charles had been a good father to her in the days before he had dissipated his fortune and started out with the intention of winning it back in the city. Those had been happy hours, Beatrice reflected.

There was nothing further in the room to call for notice. On the carpet, in contrast to the crimson ground, lay what looked like a telegram. It was half folded, but there was no mistaking the grey paper.

If there was anything wrong here, perhaps the telegram would throw a light on it. Beatrice picked up the message and flattened it on her hand. Then she read it with a puzzled face. Suddenly a flash of illumination came upon her. Her hand clenched the paper pa.s.sionately.

"Is it possible," she muttered, "that he could have known? And yet the date and the day! Why, that coward _must_ have known all the time."

A glance at the dead, placid face there recalled Beatrice to herself.

Hastily she thrust the message in her corsage and quietly left the room.

Some time had elapsed since Beatrice entered the hotel, but as yet the man she called her husband had not returned. It seemed strange, but Beatrice said nothing. She stood regarding her wedding finery with some feeling of disgust.

"I must have a room somewhere and change," she said; "it seems horrible to be walking about like this when my father is lying dead upstairs.

Mark, my woman is here somewhere. Will you try and find her and send her to Lady Rashborough for something black and quite plain? Meanwhile, I'll go to a bedroom and get some of this finery off. The mere touch of it fills me with loathing."

Beatrice's maid was discovered at length, and despatched in hot haste to Lady Rashborough's. Beatrice had scarcely entered before Stephen Richford drove up. He looked anxious and white and sullen withal, and he favoured Mark with a particularly malevolent scowl. Richford knew the relationship that had existed at one time between Mark and Beatrice.

"I suppose you must be excused under the circ.u.mstances for racing off with my wife in this fashion," he said hoa.r.s.ely. It seemed to Mark that he had found time to drink somewhere, though, as a rule, that was not one of Richford's failings. "Where is she?"

"She has gone to change," Mark said. "This is a very unfortunate business, Mr. Richford."

Richford shrugged his shoulders with an a.s.sumption of indifference. His hand trembled slightly.

"Sir Charles was getting on in years," he said; "and Sir Charles had not troubled to give very great attention to the question of his health. In fact, Sir Charles had gone it steadily. But it seems now to me that so long as the doctors are satisfied as to the cause of death----"

"I am not at all sure the doctor is satisfied," Mark said significantly.

"What's the matter?"

"Nothing, nothing," Richford stammered. "Nothing more than a twinge of that confounded neuralgia of mine."

CHAPTER VI

Beatrice came down from her room presently, dressed in quiet black. In her hand she carried not only the telegram but a letter she had taken from the dressing-table of the dead man.

The little group in the hall had by this time been augmented by the presence of Colonel Berrington; Stephen Richford had slipped off somewhere. Mark had not failed to notice the restlessness and agitation of his manner.

"I think I have got rid of everybody," Berrington said. "It has been a most distressing business, and I am afraid that there is worse to come.

Dr. Andrews has just telephoned. He has seen Sir Charles's medical man, and they have decided that there must be an inquest. I don't suggest that anything is wrong, but there you are."

"I am not surprised," Beatrice said coldly, "I have been to my father's room looking over his papers. And I found a letter that puzzles me. It was written last night as the date shows, in the hotel, on hotel paper, and evidently delivered by hand, as the envelope proves. Look at this."

Colonel Berrington held out his hand for the envelope. He started slightly as he looked at the neat, clear handwriting. Something was evidently wrong here, Mark thought. The Colonel was a man of courage, as he very well knew, and yet his fingers trembled as he glanced interrogatively at Beatrice before he drew the letter from the envelope.

"Yes," Beatrice said; "I want you to read it. I brought it down on purpose."

"There does not seem to be much," Berrington said. "As there is no heading and signature, the letter may be intended for anybody."

"Only my father's name happens to be on the envelope," Beatrice said quietly. "Pray read it aloud."

Berrington proceeded to do so. There were only two or three lines in which the writer said that she must see the recipient of the letter without delay, and that it was of no use to try and keep out of the way.

There was nothing more; no threat or sign of anger, nothing to signify that there was any feeling at all. And yet so much might have been concealed behind those simple lines. Berrington looked grave, and trembled as he handed the letter back to Beatrice.

"Clearly it is our duty to find out who wrote that letter," Mark observed. "It was written in the hotel, probably by somebody dining here last night. It is just possible that it was written by someone who was staying in the hotel. In that case we can easily ascertain the name of the writer."

"How is that possible?" Berrington demanded. He asked the question quite nervously. "In a place so large as this, with so many visitors continually going and coming----"

"There is a rigid rule here," Mark proceeded to explain. "Every guest, even if only pa.s.sing a single night under the roof, has to sign the visitors' book. With this letter in my hand I can compare signatures. If there is no signature like this characteristic handwriting, then our task is no easy one. On the other hand, if there is----"

The speaker paused significantly. Berrington's agitation deepened. With all her distress and sorrow, Beatrice did not fail to notice it.

"Perhaps you will go down to the office and see at once, Mark," Beatrice suggested.

Ventmore went off obediently enough. Berrington stood watching him for a moment, then he turned to Beatrice and laid his hand gently on her arm.

"Believe me, this is not going to help anybody," he said in a low voice.

"Unless I am greatly mistaken, I know who wrote that letter. What connection she had with your father and what the secret was between them I shall perhaps never know. But the lady who wrote that letter----"

"Ah," Beatrice cried, with a flash of sudden inspiration, "it was the grey lady, I am sure of it."

"You have guessed correctly," Berrington went on. "It was the person whom you have elected to call the grey lady. It was a great shock to me to recognize that handwriting. The secret is not wholly mine to tell, but for a long time I have been seeking the grey lady. I had not the remotest idea that she and Sir Charles had anything in common; little did I dream that she was here in this hotel last night. But whatever may be the meaning of this mystery, if there has been foul play here, the grey lady is quite innocent of it. Don't ask me to say any more, because I cannot, I dare not."

Beatrice nodded in sympathy. The brave, grave soldier by her side was terribly agitated; indeed Beatrice could not have recognized him as being capable of such a display of emotion.

"I am going to believe in you both," she said. "Probably the grey lady was the last person to see my father alive. She may have told him some terrible news; she may have given him the shock that killed him. But there was another who knew----"

"What do you mean by that?" Berrington asked.

"Nothing. I have said too much. That is quite between myself and--and could possibly have had nothing to do with my father's death. Oh, if only Mark had arrived five minutes sooner!"
