Re Tyke
It's clear I shouldn't have raised the issue in the first place, but unfortunately I did. No point denying that I'm a bit of a pedant when it comes to crossword ' liberties '. And I'm not confident of keeping my gob shut in future about this and other examples of lazy cluing.
So thanks everyone, it was fun for a while but life's too short. Dorrien, please exempt my contributions for this contest, as I shan't be checking in again.
