"A portrait of Crippen was on demand for illustration of an article on crime. The reference library had only a poor one in stock, so I went along to the waxworks

[Madame Tussaud's] and photographed Crippen's effigy. With such a perfect likeness no one would be the wiser. And to this day the picture is stiil used -- all unknowingly -- as a genuine photograph of the murderer."
