The End of Her Honeymoon

An English couple on the last day of their honeymoon arrive at a Paris hotel after midnight. Their reservations were mixed up, but the hotel owners have two separate single rooms they can use for the night. In the morning, the wife finds her husband to be missing. The hotel owners tell her she arrived alone, and imply that she is crazy. Who is telling the truth? Good mystery novel with plenty of suspense. It keeps you guessing until the end.
