I'd like to ask about the sentence below from The Adventure of the Solitary Cyclist by Conan Doyle.
The landlord further informed me that there are usually week-end visitors—‘a warm lot, sir’—at the Hall, and especially one gentleman with a red moustache, Mr. Woodley by name,
I'm not sure with the italic part, what it refers to. Is it..?
- They come very frequently. ("warm" being adverb)
- They come in large numbers. ("warm" being adverb)
- The pub's master is describing them(weekend visitors) as warm. ("warm" being adjective and "lot" being "fellow, folk")
If it's (3), what does "warm" mean in this case? Being "noisy" "excited" or even "fishy" "rich"... ?
