Dear Sirs:

I am writing to ask your help in locating my missing wife. We were on a wonderful trip to Africa for our honeymoon several months ago. On our flight back, we had a connection in England and somehow became separated. I had her paged for several hours and then contacted local and international police to assist me in locating her. To date, all of our attempts to find her have been unsuccessful.  I am now desperate to find my lost love and am trying to use the Internet to locate her. Please forward this to everyone you know so I can spread the word on locating my missing wife.

Sincerely,

 Mr. Adam Small

After a few weeks search....

Dear Mr. Small:

We have found your wife in Africa of all places. However, it is unknown how she got here, nor is she able to talk because of lockjaw, but we are under the impression that she does not want to leave. We have tried for several days to bring her back home, but she is insistent on staying here. I have enclosed a picture for you to see that she is okay, and not let you worry because she is in good hands here in this village. Please contact us if there is anything else you might want to know.
