Martell sighed. “All right. Go in the sun-room and wait, boys. The investigators will be in presently.” He sat steadily regarding his nails till his sons had departed.

Tony left them at the door. “Be with you directly,” he murmured, and hurried off along the corridor. The others went into the room, and ten minutes later the oldest of the three came in, his face blandly impassive. He went to the window and stood staring out over the skyscrapers of New York, waiting on the verge of the 21st century. He began to whistle ruminatively.

“Seth insisted on interviewing us before the detecs. Good of him.”

Young Jimmy, nervously lighting a cigarette, nodded. “Damn good. But all this. . . . I don’t understand it.”

Phil’s serious eyes were questioning. “Are you sure? There’s no doubt the authorities think one of us is a crook. I wonder—”

There was a little silence. Finally Jimmy asked, “Who is this Merlin, anyway?”

“Cleverest crook in the world,” said Tony, turning. “At least, he’s been kicking around for two years. That means a lot these days. He’s pretty much of a Robin Hood. Only kills in self-defense—and never for personal profit.”

Phil broke in, “Plenty of criminals have evaded capture for years, but they’re the small fry. Not important enough to attract attention. But the Merlin—everyone thinks he’s had years of experience. Remember when Janison died? The governor? The Merlin killed him, and nobody knew why till they found out Janison was one of the biggest political racketeers in the country. He’s a Robin Hood of sorts, but the law won’t stand for Robin Hoods.”

“And,” said Tony sardonically, “one of us is the Merlin. So they say.”

Phil grinned. “Which one?”
