Until the sun shone out, casting a long bright beam across the dingy carpet, I pondered over these curious facts in their sequence, unable to elucidate the deep mystery underlying them. After a dismal, sleepless night, haunted by a nameless spectral fear, that ray of sunshine brought back hope and banished despair I found myself at last reflecting that, after all, Dudley had expired suddenly from a cause to which any of us might be liable, and it was probable that I had been scenting mystery and tragedy where there were none. I rose, and actually smiled at the weird and horrible nature of the thoughts that throughout the wearying night had held me spellbound in indescribable dread and terror. CHAPTER FOUR. THE CLICK OF THE TELEGRAPH. When at noon, in accordance with the urgent and strangely-worded telegram I had received from the Earl of Warnham, I alighted at Horsham Station, in Sussex, I found one of the carriages from the Hall awaiting me. As I entered it, I was followed by a man I knew slightly, Superintendent Frayling, chief of the Criminal Investigation Department at Scotland Yard, who had apparently travelled down by the same train from Victoria. Greeting me, he took the place beside me, and a moment later the footman sprang upon the box and we sped away towards the open country. To my question as to his business with the Earl, he made an evasive reply, merely stating that he had received a telegram requesting an immediate interview. "This summons is rather unusual," he added, smiling. "Has anything serious occurred, do you know?" "Not that I'm aware of. Perhaps there's been a burglary at the Hall?" I suggested. "Hardly that, I think," he replied, with a knowing look, stroking his pointed brown beard. "If burglars had visited the place, he would have asked for a clever officer or two, not for a personal interview with me." With this view I was compelled to agree, then, lighting cigarettes, we sat back calmly contemplating the beautiful, fertile country through which we were driving. The road, leaving the quaint old town, descended sharply for a short distance, then wound uphill through cornfields lined by high hedges of hawthorn and holly. On, past a quaint old water-mill we skirted Warnham Pond, whereon Shelley in his youthful days sailed paper boats, then half-a-mile further entered the handsome lodge-gates of Warnham Park. Through a fine avenue, with a broad sweep of park on either side well stocked with deer, emus and many zoological specimens, we ascended, until at last, after negotiating the long, winding drive in front of the Hall, the carriage pulled up with a sudden jerk before its handsome portico. As I alighted, old Stanford, the white-haired butler, came forward hurriedly, saying,-- "His Lordship is in the library awaiting you, sir. He told me to bring you to him the moment you arrived."
