This should be simply

	(var costume isKindOf: BookMorph) ifTrue: [...]

i.e. the "class" shouldn't be there.


Also, for completeness, perhaps the "best" version would be:

	(var costume renderedMorph isKindOf: BookMorph) ifTrue: [...]

... because this will work even if the BookMorph has been rotated ;-)
