"It would be very charming," said "Harry." But the tone was merely gallant; it betokened no quickening of pulse.

"I must have a sandwich first, though," said Jennie quickly. Even she perceived that she was not making progress.

There followed eating and drinking, accompanied by a patter of gay, disconnected sallies from Jennie, relating chiefly to the eatables and drinkables. "Harry," continually appealed to by that name, remained calmly polite. Margery, when addressed, responded in monosyllables. Ripe olives and cold tongue and mustard were produced. Jennie had her cocktail, and then another. She needed stimulant, poor girl, to keep up the gay vivacity which was meeting with so little encouragement. A second bottle of beer was opened for "Harry" and Margery.

Meanwhile Merriam, still listening, was engaged also in active cogitation. He saw well enough into Crockett's thought. The latter had been momentarily convinced by his, Merriam's, well-told tale. (Margery had said he had "done fine.") But the keen, realistic mind behind those blue eyes had almost immediately rebounded and seized upon the overwhelming inherent improbability of that yarn. That there should be a man without close relationship to Norman who resembled him so strongly was in itself decidedly remarkable. That this man should encounter Norman's mistress, by pure chance, at a public dance and go home with her was even more curious. And that all this should happen, merely fortuitously, on the very night on which Senator Norman had unaccountably broken, before nine o'clock, solemn promises given with every appearance of sincerity and willingness shortly before eight, and suddenly gone over to a party for which throughout a score of years he had expressed nothing but dislike and contempt--the mathematical chances against such a series of coincidences were simply incalculable.

It was a quick, clear perception of this abstract, apriori incredibility that Merriam had read in Crockett's final glance before Jennie playfully pushed him out of the bedroom. Doubtless he was still revolving it in his mind as he sat at Jennie's table, responding with merely mechanical politeness to her rather pitiful attempts to pique his interest and desire. Well, let him revolve it. The story all hung together. What could he make of it? Little enough, probably, with the data he had now. But that was why he was lingering here at Jennie's--in the hope of getting more data. After another cocktail or two Jennie would not know what she was saying. Then he would begin to hint, to ask questions. Could Margery keep her quiet? A single word might give him a clue.

Merriam became conscious of a wish that Rockwell were at hand to help. But that wish instantly gave birth to further fears. Rockwell had said he would telephone from the hotel as soon as they arrived. That message might come any minute now--with Crockett there! Whereabouts in the flat was the telephone? He had not noticed it anywhere. He looked about the bedroom. But it was not there, of course.

Ought not that message to have come already? Surely they should be at the hotel by now unless something had gone wrong. He suddenly envisaged all the perils of discovery, which he had hitherto been too much occupied to realise, involved in the transportation of the sick Senator across the roof--down through the other trapdoor into the other hall--down three flights of stairs--along two blocks of city street to the taxi. They might so easily have been noted by some of Thompson's, or Crockett's, watchers, and followed to the hotel. Then they would be caught indeed--in the very fact. Verily, the paths of the impostor are perilous!

Then Merriam's mind was brought sharply back from these alarming excursions to his own scarcely less dangerous situation. Crockett had for the first time volunteered a remark. It was just such a remark as Merriam had anticipated.

"Nice boy you have in there."

His voice was slightly lowered but only slightly. Perhaps he did not realise the perfection of the acoustic properties of flats.
