I had not realised just what an interesting story I had picked up, when I noted on this blog that Asraf Marwan had died very suspiciously a few hundred yards from the Haymarket car bomb, some 24 hours before. The two events may well be completely unconnected, but I seem to have inspired others to some fascinating digging.
