Dear Eric
I am here to inform you that the Parker fountain pen which I borrowed from you last week has gone missing.Last night,a thief broke into my apartment and stole a few valuable items,your Parker fountain pen was one of them.I understand that the pen was irreplaceable to you as it was handed down from your grandparents,but I would like to make up for it financially while the police are investigating the case.I sincerely apologise for this unfortunate event,and please reply to me as soon as possible.
Yours Truly
Zhang Hua
