He said he tried to sneak away by going through the bathroom at the pub but she spotted him. He told her that he was already married in belgium and that she became quite insistent and then suddenly grabbed his razor that he kept in his hold all and said that if she did not take her away she would slit her throat. He said that he wasnt sure how badly she cut herself but that she cut her throat and then gave him the razor and went into the house and he then left for London walking. He said that it wasnt for a few miles that he thought to look at the razor and discovered that it had blood on it and so he threw it away.
