Proud scion of the Hawke family,
I dare not contact you directly, but we have met before, and I know you to be a person of good character and unusual ability. Indulge me in a meeting outside the city, for I require your aid in a delicate task. As a token of good faith, I have enclosed a modest sum. There will be more waiting if you can help.
Please come as soon as you receive this. If you do not, the lives of many innocents may be on my hands.
