Does this painting by Walter Sickert reveal the identity of Jack the Ripper? “The American crime novelist Patricia Cornwell was last night accused of “monstrous stupidity” for ripping up a canvas to prove that the Victorian painter Walter Sickert was Jack the Ripper.

Even in the context of the crackpot conspiracy theories, elaborate frauds and career-destroying obsessions that London’s most grisly whodunnit has spawned, Cornwell’s investigation is extreme. Not only did she have one canvas cut up in the vain hope of finding a clue to link Sickert to the murder and mutilation of five prostitutes, she spent £2m buying up 31 more of his paintings, some of his letters and even his writing desk.” Guardian UK
