The sea was utterly calm and blue in the morning sun. The dinghy rocked itself lazily in the swell of the yacht's departure. As the mist cleared away the outline of the shore became more distinct, and it appeared as if Ostend was distant scarcely a cable's length. The white dome of the great Kursaal glittered in the pale turquoise sky, and the smoke of steamers in the harbour could be plainly distinguished. On the offing was a crowd of brown-sailed fishing luggers returning with the night's catch. The many-hued bathing-vans could be counted on the distant beach. Everything seemed perfectly normal. It was difficult for either Nella or her companion to realize that anything extraordinary had happened within the last hour. Yet there was the yacht, not a mile off, to prove to them that something very extraordinary had, in fact, happened. The yacht was no vision, nor was that sinister watching figure at its stern a vision, either.
'I suppose Jules was too surprised and too feeble to inquire how Icame to be on board his yacht,' said the Prince, taking the oars.
'Oh! How did you?' asked Nella, her face lighting up. 'Really, I had almost forgotten that part of the affair.'
'I must begin at the beginning and it will take some time,' answered the Prince. 'Had we not better postpone the recital till we get ashore?'
'I will row and you shall talk,' said Nella. 'I want to know now.'
He smiled happily at her, but gently declined to yield up the oars.
'Is it not sufficient that I am here?' he said.
'It is sufficient, yes,' she replied, 'but I want to know.'
With a long, easy stroke he was pulling the dinghy shorewards.
She sat in the stern-sheets.
'There is no rudder,' he remarked, 'so you must direct me. Keep the boat's head on the lighthouse. The tide seems to be running in strongly; that will help us. The people on shore will think that we have only been for a little early morning excursion.'
'Will you kindly tell me how it came about that you were able to save my life, Prince?' she said.
'Save your life, Miss Racksole? I didn't save your life; I merely knocked a man down.'
'You saved my life,' she repeated. 'That villain would have stopped at nothing. I saw it in his eye.'
'Then you were a brave woman, for you showed no fear of death.'
His admiring gaze rested full on her. For a moment the oars ceased to move.
She gave a gesture of impatience.
'It happened that I saw you last night in your carriage,' he said. 'The fact is, I had not had the audacity to go to Berlin with my story. Istopped in Ostend to see whether I could do a little detective work on my own account.
It was a piece of good luck that I saw you. I followed the carriage as quickly as I could, and I just caught a glimpse of you as you entered that awful house. I knew that Jules had something to do with that house. I guessed what you were doing. I was afraid for you. Fortunately I had surveyed the house pretty thoroughly. There is an entrance to it at the back, from a narrow lane. I made my way there. I got into the yard at the back, and I stood under the window of the room where you had the interview with Miss Spencer. Iheard everything that was said. It was a courageous enterprise on your part to follow Miss Spencer from the Grand Babylon to Ostend. Well, I dared not force an entrance, lest I might precipitate matters too suddenly, and involve both of us in a difficulty. Imerely kept watch. Ah, Miss Racksole! you were magnificent with Miss Spencer; as I say, I could hear every word, for the window was slightly open. I felt that you needed no assistance from me.
