A man... willing to chances, wanted for an out-of-the-ordinary job which can be performed only once. "A reader found this offer very nice and write to the advertiser. But being a bit suspicious , he gave a false name. Soon afterwards, he received a reply. Enclosed in the envelope was a typed note instructing him to ring a certain number if he was still interested.

At the same time he would prepare his wife by telling her that a young man was going to call. After the murder they would meet again outside a railway station and the money would be paid as arranged. The second meeting never took place, for the advertiser was arrested shortly afterwards and charged with attempting to persuade someone to murder his wife.
