All through the spring Amory had kept up an intermittent correspondence with Isabelle Borge, punctuated by violent squabbles and chiefly enlivened by his attempts to find new words for love. He discovered Isabelle to be discreetly and aggravatingly unsentimental in letters, but he hoped against hope that she would prove not too exotic a bloom to fit the large spaces of spring as she had fitted the den in the Minnehaha Club. During May he wrote thirty-page documents almost nightly, and sent them to her in bulky envelopes exteriorly labelled "Part I" and "Part II."
