When Carnes had finished, Dr. Bird sat for a time in concentrated thought.
"You did exactly right in coming to me, Carnes," he said presently. "I don"t think that this is a job for a doctor at all--I believe that it needs a physicist and a chemist and possibly a detective to cure him.
We"ll get busy."
"What do you mean, Doctor?" demanded Carnes. "Do you think that some exterior force is causing the President"s disability?"
"I think nothing, Carnes," replied the Doctor grimly, "but I intend to know something before I am through. Don"t ask for explanations: this is not the time for talk, it is the time for action. Can you get me into the White House to-night?"
"I doubt it, Doctor, but I"ll try. What excuse shall I give? I am not supposed to have told you anything about the President"s illness."
"Get Bolton, your chief, on the phone and tell him that you have talked to me when you shouldn"t have. He"ll blow up, but after he is through exploding, tell him that I smell a rat and that I want him down here at once with _carte blanche_ authority to do as I see fit in the White House. If he makes any fuss about it, remind him of the fact that he has considered me crazy several times in the past when events showed that I was right. If he won"t play after that, let me talk to him."
"All right, Doctor," replied Carnes as he picked up the scientist"s telephone and gave the number of the home of the Chief of the Secret Service. "I"ll try to bully him out of it. He has a good deal of confidence in your ability."
Half an hour later the door of Dr. Bird"s laboratory opened suddenly to admit Bolton.
"h.e.l.lo, Doctor," exclaimed the Chief, "what the d.i.c.kens have you got on your mind now? I ought to skin Carnes alive for talking out of turn, but if you really have an idea, I"ll forgive him. What do you suspect?"
"I suspect several things, Bolton, but I haven"t time to tell you what they are. I want to get quietly into the White House as promptly as possible."
"That"s easy," replied Bolton, "but first I want to know what the object of the visit is."
"The object is to see what I can find out. My ideas are entirely too nebulous to attempt to lay them out before you just now. You"ve never worked directly with me on a case before, but Carnes can tell you that I have my own methods of working and that I won"t spill my ideas until I have something more definite to go on than I have at present."
"The Doctor is right, Chief," said Carnes. "He has an idea all right, but wild horses won"t drag it out of him until he"s ready to talk.
You"ll have to take him on faith, as I always do."
Bolton hesitated a moment and then shrugged his shoulders.
"Have it your own way, Doctor," he said. "Your reputation, both as a scientist and as an unraveller of tangled skeins, is too good for me to boggle about your methods. Tell me what you want and I"ll try to get it."
"I want to get into the White House without undue prominence being given to my movements, and listen outside the President"s door for a short time. Later I will want to examine his sleeping quarters carefully and to make a few tests. I may be entirely wrong in my a.s.sumptions, but I believe that there is something there that requires my attention."
"Come along," said Bolton. "I"ll get you in and let you listen, but the rest we"ll have to trust to luck on. You may have to wait until morning."
"We"ll cross that bridge when we get to it," replied the Doctor. "I"ll get a little stuff together that we may need."
In a few moments he had packed some apparatus in a bag and, taking up it and an instrument case, he followed Bolton and Carnes down the stairs and out onto the grounds of the Bureau of Standards.
"It"s a beautiful moon, isn"t it?" he observed.
Carnes a.s.sented absently to the Doctor"s remark, but Bolton paid no attention to the luminous disc overhead, which was flooding the landscape with its mellow light.
"My car is waiting," he announced.
"All right, old man, but stop for a moment and admire this moon,"
protested the Doctor. "Have you ever seen a finer one?"
"Come on and let the moon alone," snorted Bolton.
"My dear man, I absolutely refuse to move a step until you pause in your headlong devotion to duty and pay the homage due to Lady Luna. Don"t you realize, you benighted Christian, that you are gazing upon what has been held to be a deity, or at least the visible manifestation of deity, for ages immemorial? Haven"t you ever had time to study the history of the moon-worshipping cults? They are as old as mankind, you know. The worship of Isis was really only an exalted type of moon worship. The crescent moon, you may remember, was one of her most sacred emblems."
Bolton paused and looked at the Doctor suspiciously.
"What are you doing--pulling my leg?" he demanded.
"Not at all, my dear fellow. Carnes, doesn"t the sight of the glowing orb of night influence you to pious meditation upon the frailty of human life and the insignificance of human ambition?"
"Not to any very great degree," replied Carnes dryly.
"Carnesy, old dear, I fear that you are a cra.s.s materialist. I am beginning to despair of ever inculcating in you any respect for the finer and subtler things of life. I must try Bolton. Bolton, have you ever seen a finer moon? Remember that I won"t move a step until you have carefully considered the matter and fully answered my question."
Bolton looked first at the Doctor, then at Carnes, and finally he looked reluctantly at the moon.
"It"s a fine one," he admitted, "but all full moons look large on clear nights at this time of the year."
"Then you _have_ studied the moon?" cried Dr. Bird with delight. "I was sure--"
He broke off his speech suddenly and listened. From a distance came the mournful howl of a dog. It was answered in a moment by another howl from a different direction. Dog after dog took up the chorus until the air was filled with the melancholy wailing of the animals.
"See, Bolton," remarked the Doctor, "even the dogs feel the chastening influence of the Lady of Night and repent of the sins of their youth and the follies of their manhood, or should one say doghood? Come along. I feel that the call of duty must tear us away from the contemplation of the beauties of nature."
He led the way to Bolton"s car and got in without further words. A half-hour later, Bolton led the way into the White House. A word to the secret service operative on guard at the door admitted him and his party, and he led the way to the newly constructed solarium where the President slept. An operative stood outside the door.
"What word, Brady?" asked Bolton in a whisper.
"He seems worse, sir. I doubt if he has slept at all. Admiral Clay has been in several times, but he didn"t do much good. There, listen! The President is getting up again."
From behind the closed door which confronted them came sounds of a person rising from a bed and pacing the floor, slowly at first, and then more and more rapidly, until it was almost a run. A series of groans came to the watchers and then a long drawn out howl. Bolton shuddered.
"Poor devil!" he muttered.
Dr. Bird shot a quick glance around.
"Where is Admiral Clay?" he asked.
