Helen sends a letter to Elysium addressed to 'S. Perez'.
'Dear Ms. Perez !
I've decided to come back to your offer of help involving the ongoing investigation. I'd like you to keep an eye on the antique shop and report on unusual going-ons for the time being.
As before, the most important part is avoiding capture, so if you're exposed, don't press the situation and retreat.
Best regards,
H. Kingsley.'
