Nothing. The edge of the pad came under her seeking fingers. Nothing. She replaced the pad where she had found it, feeling a sense of urgency.

Something in the position of the pad? she wondered.

But Hawat had been over this room, doubtless had moved the pad. She looked at the leaf above the pad. The leaf! She brushed a finger along the under surface, along the edge, along the stem. It was there! Her fingers detected the subtle coded dots, scanned them in a single passage:

"Your son and Duke are in immediate danger. A bedroom has been designed to attract your son. The H loaded it with death traps to be discovered, leaving one that may escape detection." Jessica put down the urge to run back to Paul; the full message had to be learned. Her fingers sped over the dots; "I do not know the exact nature of the menace, but it has something to do with a bed. The threat to your Duke involves defection of a trusted companion or lieutenant. The H plan to give you as gift to a minion. To the best of my knowledge, this conservatory is safe. Forgive that I cannot tell more. My sources are few as my Count is not in the pay of the H. In haste, MF."

Jessica thrust the leaf aside, whirled to dash back to Paul. In that instant, the airlock door slammed open. Paul jumped through it, holding something in his right hand, slammed the door behind him. He saw his mother, pushed through the leaves to her, glanced at the fountain, thrust his hand and the thing it clutched under the falling water.

"Paul!" She grabbed his shoulder, staring at the hand. "What is that?"

He spoke casually, but she caught the effort behind the tone: "Hunter-seeker. Caught it in my room and smashed its nose, but I want to be sure. Water should short it out."

"Immerse it!" she commanded.

He obeyed.

Presently, she said: "Withdraw your hand. Leave the thing in the water."

He brought out his hand, shook water from it, staring at the quiescent metal in the fountain. Jessica broke off a plant stem, prodded the deadly sliver.

It was dead.

She dropped the stem into the water, looked at Paul. His eyes studied the room with a searching intensity that she recognized--the B.G. Way.

"This place could conceal anything," he said.

"I've reason to believe it's safe," she said.

"My room was supposed to be safe, too. Hawat said--"

"It was a hunter-seeker," she reminded him "That means someone inside the house to operate it. Seeker control beams have a limited range. The thing could've been spirited in here after Hawat's investigation."

But she thought of the message of the leaf: " . . . defection of a trusted companion or lieutenant." Not Hawat, surely. Oh, surely not Hawat.

"Hawat's men are searching the house right now," he said. "That seeker almost got the old woman who came to wake me."

"The Shadout Mapes," Jessica said, remembering the encounter at the stairs.

"A summons from your father to--"

"That can wait," Paul said. "Why do you think this room's safe?"

She pointed to the note, explained about it.

He relaxed slightly.

But Jessica remained inwardly tense, thinking: A hunter-seeker! Merciful Mother! It took all her training to prevent a fit of hysterical trembling.

Paul spoke matter of factly: "It's the Harkonnens, of course. We shall have to destroy them."

A rapping sounded at the airlock door--the code knock of one of Hawat's corps.

"Come in," Paul called.

The door swung wide and a tall man in Atreides uniform with a Hawat insignia on his cap leaned into the room. "There you are, sir," he said. "The housekeeper said you'd be here." He glanced around the room. "We found a cairn in the cellar and caught a man in it. He had a seeker console."

"I'll want to take part in the interrogation," Jessica said.

"Sorry, my Lady. We messed him up catching him. He died."

"Nothing to identify him?" she asked.

"We've found nothing yet, my Lady."

"Was he an Arrakeen native?" Paul asked.

Jessica nodded at the astuteness of the question.

"He has the native look," the man said. "Put into that cairn more'n a month ago, by the look, and left there to await our coming. Stone and mortar where he came through into the cellar were untouched when we inspected the place yesterday. I'll stake my reputation on it."

"No one questions your thoroughness," Jessica said.

"I question it, my Lady. We should've used sonic probes down there."

"I presume that's what you're doing now," Paul said.

"Yes, sir."

"Send word to my father that we'll be delayed."

"At once, sir." He glanced at Jessica. "It's Hawat's order that under such circumstances as these the young master be guarded in a safe place." Again, his eyes swept the room. "What of this place?"

"I've reason to believe it safe," she said. "Both Hawat and I have inspected it."

"Then I'll mount guard outside here, m'Lady, until we've been over the house once more." He bowed, touched his cap to Paul, backed out and swung the door closed behind him.

Paul broke the sudden silence, saying: "Had we better go over the house later ourselves? Your eyes might see things others would miss."

"This wing was the only place I hadn't examined," she said. "I put if off to last because . . . "

"Because Hawat gave it his personal attention," he said.

She darted a quick look at his face, questioning.

"Do you distrust Hawat?" she asked.

"No, but he's getting old . . . he's overworked. We could take some of the load from him."
