How to output return code in shell?

Question

I'm trying to call a custom shell script through sh:

/bin/sh -c 'myscript.sh` >log.txt 2>&1 & echo $!

Output of this command is a PID of a created background process. I want to instruct /bin/sh to save return code of myscript.sh to some file. Is it possible?

echo $? >> /path/to/return_code

$? has the return code of the last statement in bash.

But not when it was put in the background. It's easy to miss the & in the original question.
