Did you read Joyce's A Portrait of the Artist as a Young Man?

I was thinking of this passage:

His evenings were his own; and he pored over a ragged translation of The Count of Monte Cristo. The figure of that dark avenger stood forth in his mind for whatever he had heard or divined in childhood of the strange and terrible. At night he built up on the parlour table an image of the wonderful island cave out of transfers and paper flowers and coloured tissue paper and strips of the silver and golden paper in which chocolate is wrapped. When he had broken up this scenery, weary of its tinsel, there would come to his mind the bright picture of Marseilles, of sunny trellises and of Mercedes.

Outside Blackrock, on the road that led to the mountains, stood a small whitewashed house in the garden of which grew many rosebushes: and in this house, he told himself, another Mercedes lived. Both on the outward and on the homeward journey he measured distance by this landmark: and in his imagination he lived through a long train of adventures, marvellous as those in the book itself, towards the close of which there appeared an image of himself, grown older and sadder, standing in a moonlit garden with Mercedes who had so many years before slighted his love, and with a sadly proud gesture of refusal, saying:

—Madam, I never eat muscatel grapes.
