"The information we’ve been getting on Mary Kelly is down to fifteen remaining possibles. Between now and the weekend, more data will keep coming in, and we’ll reduce that number further. In the end, we’ll have to contact the likeliest possible candidate and have my security people cover the others. I’ve fed data on the fifteen into the upgraded program Francesca’s written, using all the leads on the original Ripper we could get, from every A to Z in the libraries. We have to keep plugging away on that."
