Each solution consists of three parts:

       Date:  the date of the newspaper appropriate to the crime. For
some  reason,  the  game  never  tells  you  this! Visits: the set of
addresses  you  must visit before you are allowed to appear before the
judge.  Some  addresses  can  be  visited  by  either  Holmes  or  the
Irregulars, in which case they should be visited by the Irregulars for
a  higher  score.  Such  addresses are listed under 'Irregulars'. Some
addresses, on the other hand, must be visited by Holmes in person.
     Answers:  the  answers to supply to the judge. Only look here if
you must!
