Jack the Ripper: artist, serial killer or both?

From the Belfast Telegraph:

Walter Sickert was, according to best-selling American multi-millionaire crime writer Patricia Cornwell, the real "Jack The Ripper". This Jack-the-Bad was the murderous mystery man who terrified foggy London town, brutally savaging ladies of the night throughout his long and bloody career.

But now the selfsame Walter's drawings and paintings fill the Ulster Museum's largest art gallery in what is regarded as one of its most powerful travelling exhibitions in many years. For as Sickert fan Alistair Smith, director of the University of Manchester's world famous Whitworth Art Gallery explained on its opening night, Walter was one of the most important English artists of his time.
