Clancy gave some telephonic instruction to the man on night duty at headquarters. He even dictated a paragraph for the press. Then he went straight to bed, for the hardiest detectives must sleep, and he had a full day's work before him when next the sun rose over New York.

He summed up Meiklejohn's action correctly. The Senator did not communicate with Mulberry Street during the night, so Clancy was an early visitor at his apartment.

"The Senator is ill and can see no one," said the valet.

"No matter how ill he may be, he must see me," retorted Clancy.

"But he musn't be disturbed. I have my orders."

"Take a fresh set. He's going to be disturbed right now, by you or me.

Choose quick!"

The law prevailed. A few minutes later Senator Meiklejohn entered the library sitting-room, where the little detective awaited him. He looked wretchedly ill, but his sufferings were mental, not physical. Examined critically now, in the cold light of day, he was a very different man from the spruce, dandified politician and financier who figured so prominently among Van Hofen's guests the previous evening. Yet Clancy saw at a glance that the Senator was armed at all points. Diplomacy would be useless. The situation demanded a bludgeon. He began the attack at once.

"Why didn't you ring up Mulberry Street last night, Senator?" he said.

"I was too upset. My nerves were all in."

"You told the patrolman at Eighty-sixth Street that you were hurrying away to break the news to Mrs. Tower, yet you did not go near her?"

Meiklejohn affected to consult Clancy's card to ascertain the detective's name.

"Perhaps I had better get in touch with the Bureau now," he said, and a flush of anger darkened his haggard face.

"No need. The Bureau is right here. Let us get down to bra.s.s tacks, Senator. A woman named Rachel met you outside the Four Hundred Club at eight o'clock as you were coming out. You had just spoken to Mrs. Tower, when this woman told you that you must meet two men who would await you at the Eighty-sixth landing-stage at nine. You were to bring five hundred dollars. At nine o'clock these same men killed Mr. Tower, and you yourself admitted to me that they mistook him for you. Now, will you be good enough to fill in the blanks? Who is Rachel? Where does she live? Who were the two men? Why should you give them five hundred dollars, apparently as blackmail?"

Clancy was exceedingly disappointed by the result of this thunderbolt.

Any ordinary man would have shrivelled under its crushing impact. If the police knew so much that might reasonably be regarded as secret, of what avail was further concealment? Yet Senator Meiklejohn bore up wonderfully. He showed surprise, as well he might, but was by no means pulverized.

"All this is rather marvelous," he said slowly, after a long pause. He had avoided Clancy's gaze after the first few words, and sank into an armchair with an air of weariness that was not a.s.sumed.

"Simple enough," commented the detective readily. Above all else he wanted Meiklejohn to talk. "I was on duty outside the club, and heard almost every word that pa.s.sed between you and Rachel."

"Well, well."

The Senator arose and pressed an electric bell.

"If you don't mind," he explained suavely, "I'll order some coffee and rolls. Will you join me?"

This was the parry of a skilled duelist to divert an attack and gain breathing-time. Clancy rather admired such adroitness.

"Sorry, I can't on principle," he countered.

"How--on principle?"

"You see, Senator, I may have to arrest you, and I never eat with any man with whom I may clash professionally."

"You take risks, Mr. Clancy."

"I love 'em. I'd cut my job to-day if it wasn't for the occasional excitement."

The valet appeared.

"Coffee and rolls for two, Phillips," said Meiklejohn. He turned to Clancy. "Perhaps you would prefer toast and an egg?"

"I have breakfasted already, Senator," smiled the detective, "but I may dally with the coffee."

When the door was closed on Phillips, his master glanced at a clock on the mantelpiece. The hour was eight-fifteen. Some days elapsed before Clancy interpreted that incident correctly.

"You rose early," said the Senator.

"Yes, but worms are coy this morning."

"Meaning that you still await answers to your questions. I'll deal with you fully and frankly, but I'm curious to know on what conceivable ground you could arrest me for the murder of my friend Ronald Tower."

"As an accessory before the act."

"But, consider. You have brains, Mr. Clancy. I am glad the Bureau sent such a man. How can a bit of unthinking generosity on my part be construed as partic.i.p.ation in a crime?"

"If you explain matters, Senator, the absurdity of the notion may become clear."

"Ah, that's better. Let me a.s.sure you that my coffee will not affect your fine sensibilities. Miss Rachel Craik is a lady I have known nearly all my life. I have a.s.sisted her, within my means. She resides in East One Hundred and Twelfth Street, and the man about whom she was so concerned last night is her brother. He committed some technical offense years ago, and has always been a ne'er-do-well. To please his sister, and for no other reason, I undertook to provide him with five hundred dollars, and thus enable him to start life anew. I have never met the man. I would not recognize him if I saw him. I believe he is a desperate character; his maniacal behavior last night seems to leave no room for doubt in that respect. Don't you see, Mr. Clancy, that it was I, and not poor Tower, whom he meant attacking? But for idle chance, it is my corpse, not Tower's, that would now be floating in the Hudson. You heard what Tower said. I did not. I a.s.sume, however, that some allusion was made to the money--which, by the way, is still in my pocketbook--and Tower scoffed at the notion that he had come there to hand over five hundred dollars. There you have the whole story, in so far as I can tell it."

"For the present, Senator."

"How?"

"It should yield many more chapters. Is that all you're going to say?

For instance, did you call on Rachel Craik after leaving Eighty-sixth Street?"

Meiklejohn's jaws closed like a steel trap. He almost lost his temper.

"No," he said, seemingly conquering the desire to blaze into anger at this gadfly of a detective.

"Sure?"

"I said 'no.' That is not 'yes.' I was so overcome by Tower's miserable fate that I dismissed my car and walked home. I could not face any one, least of all Helen--Mrs. Tower."

"Or the Bureau?"

"Mr. Clancy, you annoy me."

Clancy stood up.

"I must duck your coffee, Senator," he said cheerfully. "Is Miss Craik on the phone?"

"No. She is poor, and lives alone--or, to be correct, with a niece, I believe."
