I think that the 6th installment from the Chroniques du plateau Mont-Royal did not need to be written. Nothing profoundly new about the characters or their situation is revealed here, nothing added to what a reader already knows from reading the first 5. What happens in book 6 could be summed up in one sentence in an epilogue to the book 5. The only new element we learn is the name of the "grosse femme" and her ethnic background, but there is no real reason for breaking the series tradition of leaving her nameless and lifting her off the ground this way. What adds to inconsistency is the absence of Edouard, a person who was deeply in love with this lady.
