It was a lovely autumnal noontide, and the gay little town of Dinard, with its gardens rising stage above stage on the slope of the hill, its queer little bays and recesses of golden sand, was smiling in sunlight as the "Isle et Rance" steamed across the broad bay of St. Malo to the mouth of the Rance. There are few prettier rivers than this little Rhine of Brittany, and Edward Heathcote had loved it well in days gone by. But to-day he sat upon the bridge smoking his cigar, and gazing at the green hills and hanging woods, the villas and villages, and craggy cliffs and ever-varying shore, without seeing the objects upon which his eyes seemed to rest. The nearer he came to the task of investigation, the more irksome became his duty. His heart failed him as he took out the silver locket, and read the name upon the paper inside. It was the name of the woman who was to enlighten him about the dead girl, who was perhaps to put in his hand the clue which would lead him straight to the murderer. And yet who could say that he would find Sister Gudule de la Miséricorde at Dinan? He did not even know the name of the convent in which she lived. She might be dead. And yet the date of the inscription was but two years old. There was every chance that the Sister still lived: and he must be dull if he failed to find her. He stopped at the first church to which he came after leaving the boat--an old church in the lower part of the town. Here he asked his way to the presbytery, and called upon the priest, who told him that there was only one educational convent in Dinan, the Convent of St. Elizabeth of Hungary, an Ursuline convent situated in a quiet quarter of the town. Mr. Heathcote left his portmanteau at one of the hotels in the market-place, and drove at once to the convent. It was a large white building, with plastered walls, far from beautiful in itself, and showing every sign of poverty; but the gardens were neatly kept, the rooms were exquisitely clean, and the clumsy old Breton furniture was polished to the highest degree. Mr. Heathcote was received in the convent parlour by the Reverend Mother, a homely little tub-shaped personage, in a black serge habit and a picturesque white cap, which concealed every vestige of hair upon her broad intelligent forehead. She had kindly black eyes, and a frank benevolent smile, and Heathcote felt at once at his ease with her. She looked a little disappointed when, in answer to her preliminary question, he told her that he had not come to offer a new pupil. The pupils were the chief source of revenue for the convent, albeit the _pension_ was of the smallest. "Have you ever seen that locket before, madame?" he asked, laying the silver medallion before the Reverend Mother. "I have seen many such," she answered. "The Holy Father allows us to dispose of them for the benefit of the convent." "There is a little paper inside with some writing. Will you look at it, please?"
