"My dear, how can you suggest such a thing," retorted the other, "they are so common."

"Silence there!"

And once more the cackling geese were still.

CHAPTER XXV

THE FOG WAS DENSE, I COULDN'T RIGHTLY SEE

The curtain went up on the first act of the play. It was not perhaps so interesting from the outset as the audience would have wished, and the fashionable portion thereof showed its impatience by sundry coughings and whisperings, which had to be peremptorily checked now and again by a loud:

"Silence, there!" and a threat to clear the court.

The medical officer was giving his testimony at great length as to the cause of death. Technical terms were used in plenty, and puzzled the elegant ladies who had come here to be amused. The jury listened attentively, and the coroner--himself a medical man--asked several very pertinent questions:

"The thrust," he asked of Doctor Blair, who was medical officer of the district, "through the neck was effected by means of a long narrow instrument, with two sharp edges, a dagger in fact?"

"A dagger or a stiletto or a skewer," replied the doctor. "Any sharp, two-edged instrument would cause a wound like the one in the neck of the deceased."

"Was death instantaneous?"

"Almost so."

He explained at some length the intricacies of the human throat at the points where the murderer's weapon had entered the neck of his victim. Louisa listened attentively. Every moment she expected to see the coroner's hand wandering to the piece of green baize in front of him, and then drawing it away disclosing a snake-wood stick with silver ferrule stained, and showing the rise of the dagger, sheathed within the body of the stick. Every moment she expected to hear the query:

"Is this the instrument which dealt the blow?"

But this apparently was not to be just yet. The opaque veil of green baize was not to be lifted; that certain long Something was not to be revealed, the Something that would condemn Luke irrevocably, absolutely, to disgrace and to death.

Only one of the members of the jury--Louisa understood that he was the foreman--asked a simple question:

"Would," he said, "the witness explain whether in his opinion the--the unknown murderer--the--I mean----"

He floundered a little in the phrase, having realized that in his official capacity he must keep an open mind--and in that open mind of an English juryman there could for the present dwell no certainty that a murderer--an unknown murderer--did exist.

They were all here--he and the others and the coroner--in order to find out if there had been a murder committed or not.

The coroner, one elbow on the table, one large hand holding firmly the somewhat fleshy chin, looked at the juryman somewhat contemptuously.

"You mean?" he queried with an obvious effort at patience.

"I mean," resumed the man more firmly, "in this present instance, would a certain medical or anatomical knowledge be necessary in order to strike--er--or to thrust--so precisely--just on the right spot to cause immediate death?"

With amiable condescension the coroner put the query to the witness in more concise words.

"No, no," replied the doctor quickly, now that he had understood the question, "the thrust argues no special anatomical knowledge. Most laymen would know that if you pierce the throat from ear to ear suffocation is bound to ensue. It was easily enough done."

"When the deceased's head was turned away?" asked the coroner.

"Why, yes--to look out on the fog, perhaps; or at a pa.s.ser-by. It would be fairly easy if the would-be murderer was quick and determined and the victim unsuspecting."

And Doctor Blair, with long tapering fingers, pointed toward his own throat, giving ill.u.s.tration of how easily the deed might be done.

"Given the requisite weapon of course."

After a few more courteous questions of a technical kind, the first witness was dismissed--only momentarily, for he would be required again--when the green baize would be lifted from the hidden Something which lay there ready to hand, and the medical man be asked to p.r.o.nounce finally whether indeed the dagger stick was the requisite weapon for the deed which had been so easy of accomplishment.

The chauffeur who had driven the taxicab was the next witness called.

A thick-set man, in dark blue Melton coat and peaked cap, he came forward with that swinging gait which betrayed the ex-coachman.

He gave his evidence well and to the point. He had been hailed on the night in question by two gentlemen in evening dress. It was in Shaftesbury Avenue, just opposite the Lyric Theatre, and a little while after he had heard St. Martin's Church clock strike nine o'clock. "The fog was so dense," he added, "you could not see your hand before your eyes."

He had just put down at the Apollo and had crossed over to the left, going down toward Piccadilly, when the two swells hailed him from the curb. He couldn't rightly see them, because of the fog, but he noticed that both wore high hats and the collars of their overcoats ware turned up to their ears. He hardly saw their faces, but he noticed that one of them carried a walking stick.

"Or it might 'ave been a umbrella," he added after a moment's hesitation, "I couldn't rightly say."

"You must have seen the faces of your fares," argued the coroner, "if you saw that one of them carried a walking stick--or an umbrella. You must have seen something of their faces," he reiterated more emphatically.

"I didn't," retorted the man gruffly. "Was you out in that there fog, sir? If you was, you'd know 'ow you couldn't see your 'and before your eyes. I saw the point of the stick--or the umbrella, I couldn't rightly say which--only because one of them gents waved it at me when 'e was 'ailing me--that's 'ow I seed the point."

The coroner allowed the question of identification to drop: clearly nothing would be got out of the man. The gentlemen, he declared, entered the cab, and then one of them gave directions to him, putting his head out of the right hand window.

"I didn't turn to look at 'im," he said bluntly. "I could 'ear 'is voice plain enough--so why should I take a look at 'im? 'Ow did I know there was a goin' to be murder done in my cab, and me wanted to say what the murderer looked like?"

He looked round the room defiantly, as if expecting applause for this display of sound common-sense, opposed to the coroner's tiresome officialism.

"And what directions," asked the latter, "did the gentleman give you?"

"To go along Piccadilly," replied the witness, "till 'e told me to stop."

"And when did he tell you to stop?"

"By the railings of Green Park, just by 'Yde Park Corner. One of 'em puts 'is 'ead out of the window and calls to me to pull up."

"Which you did?"

"Which I did, and one of 'em gets out and standin' on the curb 'e leans back to the interior of the cab and says: S'long--see you to-morrow,' and then 'e says to me: 'No. 1 Cromwell Road,' and disappears in the fog."

"Surely you saw him then?"

"No. The fog was like pea soup there, though it looked clearer on Knightsbridge away. And 'e got out left side of course. I was up on my box right 'and side--a long way from 'im. I could see a man standin'

there, but not 'is face. 'Is 'at was pulled down right over 'is eyes, and 'is coat collar up to 'is ears."

"Had he his stick--or umbrella--with him then?"
