Filter on a deep model association

Hi,
I have these 3 associated models :

class Author extends AppModel {
var $hasAndBelongsToMany = array('Book');
}

class Book extends AppModel {
var $belongsTo = array('Collection');
var $hasAndBelongsToMany = array('Author');
}

class Collection extends AppModel {
var $hasMany = array('Book');
}

I need to find the list of all the authors (with their associated
books) filtered by collection. I tried with the containable behaviour
but I can only filters on the Collection level.
Any help would be appreciated.
