'I wonder who it can be?' she had murmured before I began my description, and I kept a secret watch upon her features, while I said:

'He is a tall young fellow, and very straight and square-shouldered, though somewhat slender. He is blond, with close-cropped hair that is quite light, almost golden, and inclined to curl where it has attained an inch of growth. He wears a moustache that is but little darker than his hair, and is kept close-trimmed. He has a broad, full forehead; honest, open blue eyes, not pale blue, but a fine deep colour, and they meet one frankly and fearlessly. His mouth is really too handsome for a man, but his chin is firm enough to counterbalance that. His manners are fine, and he has evidently been reared a gentleman. I chanced to hear him sing last night, and he has a wonderfully high tenor voice—an unusual voice; clear and sweet, and soft in the highest notes.'

Before I had finished my description, I saw clearly that she recognised the picture. Her colour had changed and changed again, from red to pale. But I made no pause, telling how I had seen him in conversation with the little brunette, and what he had told me of that conversation, and then I described the adventure of the previous night.

When I had reached the point where I had offered my card and he had refused to give me a false name, I saw her eyes glow and her head lift itself unconsciously; when I described him in converse with the wily brunette, a slight frown crossed her face, and her little foot tapped an impatient tattoo quite unconsciously; when I pictured him as following the two women toward the Wooded Island, her head was lifted again and her lip curled scornfully. But when I had reached the point where the two figures, springing suddenly from the darkness behind him, had hurled him over the parapet into the deepest part of the lagoon, a low moan burst from her lips, and she put out her hands entreatingly.

'Was he——Quick! tell me!'

'He was rescued, unconscious but living, by two of the emergency crew who guard the lagoons by night, who, luckily, were lying in their skiff under the shadow of the bridge engaged in watching the mysterious movements of the very men who were lurking behind the big pedestal on the other side of the pier, awaiting the signal from the women, their confederates. In going over, his head was quite seriously hurt. At first it was thought that he had struck the edge of the boat in falling, but the doctor says it was a blow from some blunt instrument with a rounded end—some manner of club, no doubt.'

'And now—how—is he?' she faltered.

'In very good hands, and doing as well as can be expected. I was not allowed to see him, and he does not seem fully conscious, although the doctor says he may recover if all goes well.'

'Where is he?' Her face was very pale, but there was a change in her voice, a sudden firmness, and a total lack of hesitancy.

'At the Emergency Hospital in the Fair grounds.' I had purposely made his case as serious as I consistently could, and I now made the important plunge. 'Miss Jenrys, I have taken a great interest in this young man from the first. He is a fine fellow, and now, added to this personal liking, is the duty I owe this helpless young man, who evidently has an enemy, and that enemy seemingly the very person who has been dogging you so persistently and so mysteriously. You see the strangeness of the complication. Are you willing to help me?'
