Interpretation of Murder.

Sticking plasters in 1909?

Dear Mr Rubenfeld
I have just enjoyed your book and was fascinated by how much research must have been done into the historical detail.I was however immediately suspicious of the fact that Mrs Biggs put a plaster on George Banwell's head on page 470. When I looked up the history of the sticking plaster on the internet I found out that Earle Dickson invented the adhesive bandage as they called it in 1920. He was an employer of Johnson and Johnson in the US. I guess this developed into the Elastoplast. Do you realise this error? You do encourage readers to point out any possible mistakes!
