within an ace

[vil]

Dear teachers,

Would you tell me whether I am right with my interpretation of the expression in bold in the following sentence?

Yet a man it was, I could no longer be in doubt about that. I began to recall that I had heard of cannibals. I was within an ace of calling for help. (R. I. Stevenson, “The Treasure Island”)

within an ace = almost, close to, by a hair’s breadth; on the verge , on the brink

Thank you for your efforts.

Regards,

V

You are correct.

You certainly read a wide range of literature, Vil.

I'm surprised you have the time.
