I have a question about a sentence from Sherlock Holmes's series "The Adventure of the Three Students". Here it goes.
He was nearly expelled over a card scandal in his first year.
Can anyone be specific on this "card scandal"? I guess this can't be getting at something like "card fraud" because the novel's setting's in the 20th century. So it maybe what "he" did was playing cards for money. Or, I heard "card"can mean "big, famous" as an adjective, so it's like "He had a big scandal last year and nearly expelled". Can anyone tell me? Thank you.
