Tony,
I had not visited your home page before - very impressive and a great 
way to publish annecdores,  tips and advice coming from experience, 
but wich would not otherwise  be accesible in print.
Flattered that you had picked up the benzidine case.  Thr backdrop to 
the story was even more interesting.
The Chief police officer in  Salisbury (for thst is where the murder took 
plave) had NEVER before been involved in a homicide
Also, Salisbury had not had a homicide for 30 years previously
and
A business woman just driving thru' was murdered in a public 
conveience the same night!! and NOT by the same individual.

Best wishes, especially if you do not mention cricket or rugby
