Hi I’d like to ask about the sentence from The Devil’s Foot by Conan Doyle.
“Against the charge of killing Mortimer Tregennis.” Sterndale mopped his forehead with his handkerchief. “Upon my word, you are getting on,” said he. “Do all your successes depend upon this prodigious power of bluff?”
This is when Holmes was prosecuting an antagonist who he thought to be the perpetrator.
Could anyone paraphrase the antagonist’s wording “You are getting on” here?
Is this like “You’re getting on (my nerves)”, that is, you’re annoying?
Or I heard “to get on” can mean “to get old”, so the antagonist is bluffing like “You’re getting old and have lost the edge Holmes, because you’re way off the base”?
Or the antagonist is being sarcastic and saying “You are doing very good!” by this phrase? I don’t know. Can anyone tell me how I should interpret the phrasal verb “get on” in this context please? Thank you in advance.
