"It's a good bluff," Gates chuckled, "but they don't intend leaving it there for long, sir. I'd say we'd better fire now, Mr. Thomas, and when they stop we'll have a little chat with 'em." Tommy sprang up and pulled the string, and our eyes were dazzled, our ears jarred, with a perfectly glorious explosion that lighted up the sea for a hundred yards. "Whiz-bang!" Tommy yelled. "I wish I had this thing in Kentucky! It'd work wonders for the Democrats!" Nothing happened aboard the _Orchid_. She did not vary her course an inch. The sailor at the helm had given a frantic jump when Miss Nancy went off, but resumed his place evidently aware that no missiles had been fired. "Load her up again," I urged. "Let's keep on till they get mad!" Bilkins passed out the shells and the piece was loaded and fired, loaded and fired, till we seemed surely to have waked old Nep himself. I do not know how many rounds we shot but it must have continued for some time, thoroughly engrossing us. Now suddenly the stern light went out, and immediately afterwards the portholes, losing their glow, became as nothing. The tropical night, always swift in coming, had fallen more stealthily than we realized, and the yacht melted into darkness. "_Sacre bleu!_" Monsieur raged--for the night was overcast and as black as sin. But Gates was already stripping the searchlight of its cover. When he had swung open the big lens Tommy struck a match, which blew out. His second was blown out by a hiss of air that preceded the flow of gas, and the professor jumbled matters by trying his hand. But these efforts scarcely took more time than the telling, and when the powerful streak of light finally pierced the darkness the very first thing it showed us was a white sail. "I shouldn't have worried about night catching us, sir, if I'd thought of this before," Gates laughed. "And there's plenty of extra acetylene tanks, too, so she carn't get away now!" "You'll have to haul down some sail, though," I replied, seeing that the _Orchid_ lay nearly abeam of us. "No quicker said than done, sir." He went to direct this, while we held our light squarely on the fleeing outlaw. Nobody was astir about her deck; indeed, so undisturbed did she appear that the sailor standing statue-like at her wheel might have been the only living thing aboard. I breathed fast with thinking that maybe Sylvia might come up, and my senses were so alert, my mind, eyes, ears so intently reaching toward her, that now I heard what was indeed a most unexpected sound: a piano. Grasping Tommy's arm I whispered this to him, and he nodded, saying in a low tone: "Yes, I hear it plainly. Reminds me of Monsieur's master musician playing a rhapsody in the dark, d'you remember? Listen! Gods, it's '_De puis le jour_,' from Louise!" Yet in the next breath he added: "Cheerful girl you have, Jack,--she's switched off from her love song to Chopin's funeral march!"
