I have been working for some months on a Jack the Ripper book (& previously unconsidered suspect). I have a copy of the Writers' & Artists' Yearbook, but many publishers won't consider "unsolicited manuscripts" by which, i gather, they mean those not submitted through agents. I have been in contact with one of the latter who has decided not to take the matter on because he feels that my evidence, though strong, isn't quite strong enough. Are there any publisher's out there whom anyone can recommend?
