Lestrade and Gregson glanced at each other with an incredulous smile.
"If this man was murdered, how was it done?" asked the former.
"Poison," said Sherlock Holmes curtly, and strode off. "One other thing, Lestrade," he added, turning round at the door: "'Rache,' is the German for 'revenge;' so don't lose your time looking for Miss Rachel."
With which Parthian shot he walked away, leaving the two rivals open-mouthed behind him.
IV. What John Rance Had To Tell
IT was one o'clock when we left No. 3, Lauriston Gardens. Sherlock Holmes led me to the nearest telegraph office, whence he dispatched a long telegram. He then hailed a cab, and ordered the driver to take us to the address given us by Lestrade.
"There is nothing like first hand evidence," he remarked; "as a matter of fact, my mind is entirely made up upon the case, but still we may as well learn all that is to be learned."
"You amaze me, Holmes," said I. "Surely you are not as sure as you pretend to be of all those particulars which you gave."
"There's no room for a mistake," he answered. "The very first thing which I observed on arriving there was that a cab had made two ruts with its wheels close to the curb. Now, up to last night, we have had no rain for a week, so that those wheels which left such a deep impression must have been there during the night. There were the marks of the horse's hoofs, too, the outline of one of which was far more clearly cut than that of the other three, showing that that was a new shoe. Since the cab was there after the rain began, and was not there at any time during the morning — I have Gregson's word for that — it follows that it must have been there during the night, and, therefore, that it brought those two individuals to the house."
