wounded character. Is
he not the celebrated author of The Dynamics of an Asteroid, a
book which ascends to such rarefied heights of pure mathematics
that it is said that there was no man in the scientific press
capable of criticizing it? Is this a man to traduce?
Foul-mouthed doctor and slandered professor--such would be your
respective roles! That's genius, Watson. But if I am spared by
lesser men, our day will surely come."

"May I be there to see!" I exclaimed devoutly. "But you were
speaking of this man Porlock."

"Ah, yes--the so-called Porlock is a link in the chain some
little way from its great attachment. Porlock is not quite a
sound link--between ourselves. He is the only flaw in that chain
so far as I have been able to test it."

"But no chain is stronger than its weakest link."

"Exactly, my dear Watson! Hence the extreme importance of
Porlock. Led on by some rudimentary aspirations towards right,
and encouraged by the judicious stimulation of an occasional
ten-pound note sent to him by devious methods, he has once or
twice given me advance information which has been of value--that
highest value which anticipates and prevents rather than avenges
crime. I cannot doubt that, if we had the cipher, we should find
that this communication is of the nature that I indicate."

Again Holmes flattened out the paper upon his unused plate. I
rose and, leaning over him, stared down at the curious
inscription, which ran as follows:

534 C2 13 127 36 31 4 17 21 41 DOUGLAS 109 293 5 37 BIRLSTONE 26
BIRLSTONE 9 47 171

"What do you make of it, Holmes?"

"It is obviously an attempt to convey secret information."

"But what is the use of a cipher message without the cipher?"

"In this instance, none at all."

"Why do you say 'in this instance'?"

"Because there are many ciphers which I would read as easily as I
do the apocrypha of the agony column: such crude devices amuse
the intelligence without fatiguing it. But this is different.
It is clearly a reference to the words in a page of some book.
Until I am told which page and which book I am powerless."

"But why 'Douglas' and 'Birlstone'?"

"Clearly because those are words which were not contained in the
page in question."

"Then why has he not indicated the book?"

"Yow native shrewdness, my dear Watson, that innate cunning which
is the delight of your friends, would surely prevent you from
inclosing cipher and message in the same envelope. Should it
miscarry, you are undone. As it is, both have to go wrong before
any harm comes from it. Our second post is now overdue, and I
shall be surprised if it does not bring us either a further
letter of
