onvenient to call here to-morrow at 8 a.m. I will give you the
full particulars early enough for the first edition. There is no sense
in taking up much time over so simple an affair as the Pegram case.
Good afternoon, sir."

Mr. Scribbings was too much astonished to return the greeting. He left
in a speechless condition, and I saw him go up the street with his hat
still in his hand.

Sherlaw Kombs relapsed into his old lounging attitude, with his hands
clasped behind his head. The smoke came from his lips in quick puffs at
first, then at longer intervals. I saw he was coming to a conclusion,
so I said nothing.

Finally he spoke in his most dreamy manner. "I do not wish to seem to
be rushing things at all, Whatson, but I am going out to-night on the
Scotch Express. Would you care to accompany me?"

"Bless me!" I cried, glancing at the clock, "you haven't time, it is
after five now."

"Ample time, Whatson--ample," he murmured, without changing his
position. "I give myself a minute and a half to change slippers and

seconds to the street, forty-two seconds waiting for a hansom, and then
seven at the terminus before the express starts. I shall be glad of

big clock. "I dislike having a miscalculation of that sort occur."

The great Scotch Express stood ready for its long journey. The
detective tapped one of the guards on the shoulder.

"You have heard of the so-called Pegram mystery, I presume?"

"Certainly, sir. It happened on this very train, sir."

"Really? Is the same carriage still on the train?"

"Well, yes, sir, it is," replied the guard, lowering his voice, "but of
course, sir, we have to keep very quiet about it. People wouldn't
travel in it, else, sir."

"Doubtless. Do you happen to know if anybody occupies the compartment
in which the body was found?"

"A lady and gentleman, sir; I put 'em in myself, sir."

"Would you further oblige me," said the detective, deftly slipping
half-a-sovereign into the hand of the guard, "by going to the window
and informing them in an offhand casual sort of way that the tragedy
