My Year With Proust - Day 291

   The reader will remember that, well before going that day (the day on which the Princesse de Guermantes's reception was to be held) to pay the Duke and Duchess for their return and in the course of my vigil had ma a discovery which concerned M. de Charlus in particular but was in itself so important that I have until now, until the moment when I could give it the prominence and treat it with the fullness that it demanded, postponed giving an account of it.

Marcel Proust, Cities of the Plain, p. 623

And so we have moved into the fourth volume of Remembrance of Things Past, Cities of the Plain.  It opens with a story focusing on M. de Charlus, at the time "corpulent, greying, aged."  A goodly chunk of the end of The Guermantes Way featured M. de Charlus hysterically berating Marcel for a reason that largely mystified the young man.  We are about to learn a lot more about M. de Charlus and, I suspect, about Proust himself.
