The De Stancys and Powers remained in Heidelberg for some days. All remarked that after Somerset's departure Paula was frequently irritable, though at other times as serene as ever. Yet even when in a blithe and saucy mood there was at bottom a tinge of melancholy. Something did not lie easy in her undemonstrative heart, and all her friends excused the inequalities of a humour whose source, though not positively known, could be fairly well guessed.
De Stancy had long since discovered that his chance lay chiefly in her recently acquired and fanciful predilection d'artiste for hoary mediaeval families with ancestors in alabaster and primogenitive renown. Seeing this he dwelt on those topics which brought out that aspect of himself more clearly, talking feudalism and chivalry with a zest that he had never hitherto shown. Yet it was not altogether factitious. For, discovering how much this quondam Puritan was interested in the attributes of long-chronicled houses, a reflected interest in himself arose in his own soul, and he began to wonder why he had not prized these things before. Till now disgusted by the failure of his family to hold its own in the turmoil between ancient and modern, he had grown to undervalue its past prestige; and it was with corrective ardour that he adopted while he ministered to her views.
Henceforward the wooing of De Stancy took the form of an intermittent address, the incidents of their travel furnishing pegs whereon to hang his subject; sometimes hindering it, but seldom failing to produce in her a greater tolerance of his presence. His next opportunity was the day after Somerset's departure from Heidelberg. They stood on the great terrace of the Schloss-Garten, looking across the intervening ravine to the north-east front of the castle which rose before them in all its customary warm tints and battered magnificence.
'This is a spot, if any, which should bring matters to a crisis between you and me,' he asserted good-humouredly. 'But you have been so silent to-day that I lose the spirit to take advantage of my privilege.'
She inquired what privilege he spoke of, as if quite another subject had been in her mind than De Stancy.
'The privilege of winning your heart if I can, which you gave me at Carlsruhe.'
'O,' she said. 'Well, I've been thinking of that. But I do not feel myself absolutely bound by the statement I made in that room; and I shall expect, if I withdraw it, not to be called to account by you.'
De Stancy looked rather blank.
'If you recede from your promise you will doubtless have good reason. But I must solemnly beg you, after raising my hopes, to keep as near as you can to your word, so as not to throw me into utter despair.'
