"I have," said the detective. "Professor Poppelbaum sent it back with the solution. You can have a look at it, though I can't leave it with you without special authority."
He drew the document from his pocket-book and handed it to Thorndyke, who took it over to the window and scrutinized it closely. From the window he drifted into the adjacent office, closing the door after him; and presently the sound of a faint explosion told me that he had lighted the gas-fire.
"Of course," said Miller, taking up the translation again, "this gibberish is the sort of stuff you might expect from a parcel of crack-brained anarchists; but it doesn't seem to mean anything."
"Not to us," I agreed; "but the phrases may have some pre-arranged significance. And then there are the letters between the words. It is possible that they may really form a cipher."
"I suggested that to the Professor," said Miller, "but he wouldn't hear of it. He is sure they are only dummies."
"I think he is probably mistaken, and so, I fancy, does my colleague. But we shall hear what he has to say presently."
"Oh, I know what he will say," growled Miller. "He will put the thing under the microscope, and tell us who made the paper, and what the ink is composed of, and then we shall be just where we were." The superintendent was evidently deeply depressed.
We sat for some time pondering in silence on the vague sentences of the Professor's translation, until, at length, Thorndyke reappeared, holding the document in his hand. He laid it quietly on the table by the officer, and then inquired:
"Certainly," replied Miller. "I was authorized to consult you respecting the translation, but nothing was said about the original. Still, if you want it for further study, I will get it for you."
"No, thank you," said Thorndyke. "I have finished with it. My theory turned out to be correct."
"Your theory!" exclaimed the superintendent, eagerly. "Do you mean to say--?"
"And, as you are consulting me officially, I may as well give you this."
He held out a sheet of paper, which the detective took from him and began to read.
"What is this?" he asked, looking up at Thorndyke with a puzzled frown. "Where did it come from?"
"It is the solution of the cryptogram," replied Thorndyke.
