Sherlock Holmes - Deductions

“I knew, also, that he (Baron Gruner) had come to England and had a presentiment that sooner or later he would find me some work to do.” (Sherlock Holmes)
“The moment the woman told us of it I realized what a tremendous weapon was there if we could but lay our hands on it. I said nothing at the time to indicate my thoughts, for this woman might have given it away. But I brooded over it. Then this assault upon me gave me the chance of letting the Baron think that no precautions need be taken against me.” (Sherlock Holmes)
