‘A German police agent, disguised as a priest, I suppose you mean. The spy Kehler?’
He began to tremble violently. ‘But the Sister! The nurse!’
‘Sister Marie-Joseph! What do you mean?’
‘She is on board now, nursing O’Callaghan.’
It was my turn to utter an oath of consternation.
‘Come with me. Take me on board instantly, or take me to your commander.’
‘We will go on board,’ said the sobered lieutenant.
Glancing round as I followed him out I saw that Kehler had disappeared. Quickening our steps by a common instinct, the lieutenant and I almost ran down to the water’s edge.
‘Thank God!’ burst from his lips as we came in sight of the majestic vessel lying peacefully at her anchors in the calm waters of the bay, her spars and turrets outlined against the clear, starlit sky, and only a few twinkling lights betraying the presence of the two hundred men who slept below her decks. The same instant there was a spout of fire, a cloud of wreck and dust mounted to heaven, and a thunderous boom stunned our ears, and sent the waters of the bay dashing up at our feet.
The Maine had broken like a bubble. I saw all in a flash—in some dark way that will never now be revealed Sister Marie-Joseph had blown up the Maine. Kehler had succeeded—I had failed.
