The letter seemed hastily written, though legible. The penmanship wasn't the best, but it wasn't the worst one could do.
"Dear Major,
I apologise I could not deliver this personally, or simply say this directly to you, but well... things came up. I've reevaluated my situation, and I must take my leave as one of your 'foreign agents'. I can never thank you enough for the help you and your men have given myself and Seraphim, though she went missing some time ago. I have returned all Hessian property I previously had access to, and I have given your engineers at Wolfsburg the parts of value from the Former Glory. The fate of the hull, however, is of more practicality to myself - as a storage base.
Again, I apologise the circumstances did not allow me to contact you directly... If you require anything of me, you should be able to reach me via these channel codes:
