"Not only are you here under a false name, Mr. Blore, but in addition I've noticed this evening that you're a first-class liar.
You claim to have come from Natal, South Africa.
I know South Africa and Natal and I'm prepared to swear that you've never set foot in South Africa in your life."
All eyes were turned on Blore.
Angry suspicious eyes.
Anthony Marston moved a step nearer to him. His fists clenched themselves.
"Now then, you swine," he said.
"Any explanation?"
Blore flung back his head and set his square jaw.
"You gentlemen have got me wrong," he said. "I've got my credentials and you can see them.
I'm an ex-C.I.D. man.
I run a detective agency in Plymouth.
I was put on this job."
Mr. Justice Wargrave asked: "By whom?"
"This man Owen.
Enclosed a handsome money order for expenses and instructed me as to what he wanted done.
I was to join the house party, posing as a guest.
I was given all your names. I was to watch you all."
"Any reason given?"
Blore said bitterly: "Mrs. Owen's jewels.
Mrs. Owen my foot!
I don't believe there's any such person."
Again the forefinger of the judge stroked his lip, this time appreciatively.
"Your conclusions are, I think, justified," he said. "Ulick Norman Owen!
In Miss Brent's letter, though the signature of the surname is a mere scrawl the Christian names are reasonably clear - Una Nancy - in either case, you notice, the same initials. Ulick Norman Owen - Una Nancy Owen - each time, that is to say, U.N.
Owen.
Or by a slight stretch of fancy, UNKNOWN!"
Vera cried: "But this is fantastic - mad!"
The judge nodded gently.
He said: "Oh, yes.
I've no doubt in my own mind that we have been invited here by a madman - probably a dangerous homicidal lunatic."
Chapter 4
There was a moment's silence - a silence of dismay and bewilderment.
Then the judge's small clear voice took up the thread once more.
"We will now proceed to the next stage of our inquiry.
First, however, I will just add my own credentials to the list."
He took a letter from his pocket and tossed it onto the table.
"This purports to be from an old friend of mine, Lady Constance Culmington.
I hove not seen her for some years.
She went to the East.
It is exactly the kind of vague incoherent letter she would write, urging me to join her here and referring to her host and hostess in the vaguest of terms.
The same technique, you will observe. I only mention it because it agrees with the other evidence - from all of which emerges one interesting point.
Whoever it was who enticed us here, that person knows or has taken the trouble to find out a good deal about us all.
He, whoever he may be, is aware of my friendship for Lady Constance - and is familiar with her epistolary style.
He knows something about Dr. Armstrong's colleagues and their present whereabouts.
He knows the nickname of Mr. Marston's friend and the kind of telegrams he sends.
He knows exactly where Miss Brent was two years ago for her holiday and the kind of people she met there.
He knows all about General Macarthur's old cronies." He paused. Then he said: "He knows, you see, a good deal.
And out of his knowledge concerning us, he has made certain definite accusations."
Immediately a babel broke out.
