Please help me to understand the meaning of "guilty" in this context:
"He turns around and spots me.
Byron.
Once I would have done anything for Byron.‘Skye! Skye Turner – it’s you, isn’t it?’
‘Guilty,’ I say, then instantly regret it.
Byron engulfs me in his strong arms."
Excerpt from "My mother's silence" by Lauren Westwood
Suppose, her answer does not mean that she is literally guilty for returning to the place she left many years ago?

In addition to the two existing good answers, I'd like to add that the fuller version of "guilty" is "guilty as charged". The basic meaning of this phrase is the same as "guilty" as explained by Michael Harvey and jla, namely, to affirm that one is responsible for a crime that they have committed.
But there is a figurative sense that is commonly used colloquially. See Cambridge Dictionary
This has a slight implication that the thing one is being identified as can be jocularly likened to a minor offense. "You like Elvis Presley?" "Guilty!" This basically means: "Yes I am an Elvis fan. And I am proud of being one." Of course being an Elvis fan is nothing to be ashamed of, but the funny part is you are using "guilty" to imply that some people might think that, (but you are proud).
I found your source on Google Books. Fuller context:
Apparently "I" do not want to see this Byron guy and "I" didn't know he would be here, otherwise "I" wouldn't have come. Of course there are reasons why that is the case, and you will have to get it from the prior passages, but the situation described here is clear. "I" feel embarrassed and thus reluctant to see Byron, and that is implied in the use of the phrase "guilty" as a way to say "yes" (give an affirmative answer) to "It's you, isn't it!"
