Mr Perry's Adventure game works.
Don't ask how, but some how it does.
It runs in a method similar to Mr Laschelles' games, if it makes any form of sense to the GM, then he'll generally let it go.
The characters fit in well with each other and have developed an ask-me-no-questions kind of mentality, but will share information as and when it becomes necessary, and does damage any secrets they may be hiding.
I can see Dirk fitting in somehow.

Best thing you can do is just go with it. It all works out (somehow)
