Now, what does this all have to do with Patricia Cornwell?

Well, the beginning of her story takes place during the evening of August 6--only hours before Martha Tabram's body was found lying in a pool of blood in the George Yard buildings. August 6 had been a bank holiday. The streets had been full of activity--which Cornwell uses to set the stage for a little bit of innuendo.

Assuming at face value that Martha Tabram was murdered by Jack the Ripper, Cornwell mentions that during the holidy, people could buy costumes of soldiers and policemen with ease (and Martha Tabram had last been seen going off with a soldier). Well, coincidentally, Sickert had a theatrical background and enjoyed wearing costumes, and he also enjoyed disguising his identity in letters he wrote to the editors of various newspapers. (My note: the latter was a common practice at the time, with many letter writers scribbling their opinions pseudonymously).

Notice how we've travelled here from facts to innuendo, again using the underlying assumption that Sickert was the Ripper. There is no evidence that Sickert was on the streets on August 6, 1888. There is no evidence that he wasn't. There is no evidence one way or the other. Neither can Patricia Cornwell produce a receipt for Sickert's purchase of a soldier's costume. However, since he must have been Jack the Ripper and since Martha Tabram must have been killed by Jack the Ripper, then Sickert must have been on the streets that night. So how do we account for the rather inconvenient fact that the man Tabram was seen going off with was in soldier's uniform? Well, rather ingeniously, Patricia Cornwell drags out the notion that perhaps--no, definitely!--Sickert bought a costume so that he could look like a soldier. It's a bit of a stretch, but as far as Cornwell's concerned, it works.

Now, why, you ask, is it so important to Cornwell that Martha Tabram be one of the Ripper's victims? Chronology. You see, Sickert's mentor (the painter, James Abbott McNeill Whistler--yes, that Whistler) was getting married in a few days. Cornwell needs for us to believe that it was Whistler's marriage that sent Sickert over the edge into murder. Why? Well, I'll have to tell you that in the next installment because now I need to go do some other work.

But if you'd like to do some reading in the meantime, here are a couple of links to Stephen P. Ryder's amazing Casebook website:

Casebook: Jack the Ripper - Victims
Casebook: Jack the Ripper - Walter Sickert

(Oh, and yes, I did read the Casebook's primer to Cornwell's accusations... nearly a year ago, and it's brilliant. What I'm writing now, though, is based strictly upon my own examination of Cornwell's text).
