“Ah, Doctor,” she gasped breathlessly, as I greeted her and our hands met, “I am so glad I’ve found you? I went to Hammersmith, but your friend, Doctor Raymond, told me you were here.”
“What is the matter?” I inquired, surprised at her eager manner. “Has anything occurred?”
“Yes, something most mysterious!” she answered hoarsely. “You are the only doctor whom I can trust. Will you come with me at once? I have a cab in waiting.”
“Where?” I inquired. “To your house?”
“Yes,” she urged. “Do not let us lose time. Apologise to your other patients here, and come at once. It’s a matter of life or death.”
“Of life or death?” I cried. “Who is ill?”
“It’s all a mystery,” she answered in the same breathless manner. “But you will keep it a secret—promise me.”
“I have many family secrets entrusted to me,” I answered. “Rest assured that I shall betray no confidence.”
“Then come quickly, and recollect that what you may see or hear to-night you must never divulge. On your word of honour as a gentleman.”
“I give you my word of honour,” I answered, wondering what fresh mystery was in store for me.
