"I—don't quite understand," I stammered. When any sudden question about Jim is flung at me before his parents, I'm always a little scared!

"Jim and I had a bet," Mr. Curtis explained, "that he couldn't travel incog., through Europe for a given length of time, in a big auto, doing himself well everywhere, without his real name coming out. He won the bet, but he told me—after he got over a bad dose of typhoid—that he'd lost the only girl he'd ever loved or could love—lost her through that da—that stupid bet. He described the girl. I guess there aren't two of her on earth!"

"That's a mighty fine compliment, Molly!" said Father Beckett.

Just then Brian called, and I wasn't sorry, for I couldn't find the right answer for the man who had separated Jim Beckett from me. It was all I could do to get my breath.

"Why, of course, that's your brother! I might have known by the likeness. Gee, but it's great about the dog! No wonder it despised the name of 'Sherlock.' Rather a come-down from a star! There's a big story in this. Your party will have to dine with us correspondents, and talk things over. The crowd will be delighted. Say yes, Mrs. Beckett!"

I heard no more, for I was on my way to Brian. But by the time I'd thanked Dierdre, been slightly snubbed by her, and successfully presented to Sirius, it was settled that we should spend our evening at Royalieu with the correspondents. The Beckett auto was ready, but the dog's joy was too big for the biggest car, so Brian and I walked to the château, and Jack Curtis with us, to exchange stories of le grand chien policier, late "Sherlock."

Matching the new history on to the early mystery was like fitting in the lost bits of a jigsaw puzzle—bits which, when missing, left the picture void. Between Brian and the war correspondent the pattern came to life: but there's one piece in the middle which can never be restored. Only one person could supply that: a German officer, and he is no longer in this world.

Jack Curtis found the police dog, badly wounded, at a place near Paschendaele, where the Germans had temporary headquarters and had been driven out after a fierce struggle. One of the dog's legs was broken, and blood had dried on his glossy coat, but he "registered delight" (as moving picture people say) when he limped out of a half-ruined house to welcome the rush of British khaki. The few inhabitants who had lived in the village through the German occupation, knew the dog as "Siegfried," to which name he had obstinately refused to answer. His German master, a captain, whom he obeyed sullenly, always dragged him about in leash, as he never willingly kept at heel. Everyone wondered why the officer, who was far from lenient with his men, showed patience with the dog. But his orderly explained that Captain von Busche had picked up the starving animal weeks before, wandering about No Man's Land. The creature was valuable, and his dislike of the gray-green uniform had puzzled Von Busche. His failure to win the dog's affection piqued him, and in his blundering way he persevered. The people of the village were more successful. They made friends with "Siegfried," to Von Busche's annoyance; and a day or two before the hurried German retreat under bombardment, the dog was beaten for deserting his master to follow a little boy. The boy, too, was punished for his "impudence" in calling the dog. People were indignant, and there were secret murmurings about revenge.

That night, however, Fate took the matter in hand. Precisely what happened is the bit that must remain missing in the puzzle. The dog slept in the room with his master, in a house where several young officers lived close to headquarters. All of them had been out playing cards at a tavern. Von Busche returned earlier than the rest. He was seen in the street the worse for drink. He went into the house, and must have gone to his room, where the police dog had been shut up for hours in disgrace. A moment later there was a yell, then a gurgling shriek. The neighbours listened—and shrugged their shoulders. The parents of the child who had been beaten by Von Busche lived next door. They heard sounds of a scuffle; furniture falling; faint groans and deep growls. Lips dared not speak, but eyes met and said: "The dog's done what we couldn't do."

Silence had fallen long before Von Busche's fellow officers came home; such silence as that town knew, where bombardment ceased not by day or night. Before dawn, a bomb fell on the roof of the house, which till then had never been touched, and the officers all scuttled out to save themselves; all but Von Busche. Whether in the confusion he was forgotten, or whether it was thought he had not come home, no one could tell. He was not seen again till after the Germans had packed up in haste and decamped, which they did a few hours later, leaving the townsfolk to shelter in cellars. It was only when the British arrived, and Siegfried limped out from the battered house, that the dog's existence was recalled—and the sounds in the night. Then the house was searched, and Von Busche's body found, half buried under fallen tiles and plaster. There were wounds in his throat, however, not to be accounted for by the accident. The dog's broken leg was also a mystery. "I had the poor boy mended up by a jolly good surgeon," Jack Curtis finished his story. "He's as sound as ever now. He attached himself to me from the first, as if he knew he had to thank me for his cure, but he wasn't enthusiastic. I couldn't flatter myself that I was loved! I had the idea I wasn't what he wanted—that he'd like to tell me what he did want, and politely bid me good-bye forever."
