Error whilst JSON decoding string containing an escaped double quote

I’m trying to decode a string containing an escaped double quote, e.g. “I said, “Hello””

Now to do that in Elm, I may use Json.Decode as Decode:
Decode.decodeString Decode.string "\"I said, \"Hello\"\""

However, this is causing the decoder to fail. Can anyone explain why? I’d like to know how to have double quotes in my JSON string.

When you escape the quotes like that you’re ending up with:

"I said, "Hello""

And that’s not valid JSON, so you will need to escape the quotes and the backslashes:

"\"I said, \\\"Hello\\\""

Thank you so much, I got what I was doing wrong!
