Barber, the fat owner of the Scarlet Cockatoo, pressed a concealed button in the shelving of the bookcases behind his desk. He was wearing a saffron-colored suit with a blood-red tie. A section of the bookcase swung out on a noiseless pivot, revealing a small air-conditioned radio room.

Squeezing his saffron-suited bulk around the case, Barber shuffled into the hidden room. He grunted, pushed another button, and was sealed up with the radio equipment.

He seated himself before the radio set, rubbing his pudgy fingers around the circle of his beard.

While he waited for the radio to warm up, he said to himself, "Communications have never gone well on this caper. First I get cut off from McClennan. Now I can't even get a rise out of Silvera or Tinn. We'll give it another try." He spread his huge legs wide, sighing. "Sometimes I wish fate had made me more mobile. Then I could undertake field work myself. If only-"

The fat man blinked his tiny eyes and gave a surprised snort. A red bulb over the radio set had started to flash on and off. "Trouble," said Barber.

He cautiously shoved back his chair, turning toward the secret door. The red light could be set

flashing by flicking various switches around the club. It was a danger signal, meaning somebody was bringing trouble into the Scarlet Cockatoo.

Barber placed one little eye to the peephole in the secret wall. A loud knocking began on his office door.

"Barber, open up! This is the police!' The knocking continued.

"Open up, or we'll let ourselves in! We have a warrant!"

As the fat Barber watched the door of his office, it was forced open. Lieutenant Kiwanda of the Mawitaan police jumped across the threshold, pistol drawn.

Behind the lieutenant came Colonel Weeks of the Jungle Patrol, looking very angry. Then other police and JP men whom Barber didn't recognize.

Barber stayed where he was. Breathing very carefully, watching them fan out around his office.

"There's the bookcase Lemos told us about," said Colonel Weeks, pointing.

Lemos, thought Barber. So it's Lemos who betrayed me. This whole caper is going sour.

"If you're in there, come on out," called Lieutenant Kiwanda.

The left eye of Colonel Weeks, who was directly in front of the bookcase wall, seemed to be looking into Barber's eye. "Let's find the control button," said the Colonel.

A small wheeze was starting to rattle around in Barber's huge chest. He hesitated for half a moment, then punched at a button. The secret wall swung in. "Well, well, Lieutenant," he said as he stepped slowly into their range of vision. "You had better have all the right papers with you, and in perfect order. Otherwise-"

"We'd like," interrupted Lieutenant Kiwanda, "to ask you some questions about the Veiled Lady."

Wheezing, the vast man made his way back to his desk. "You want a travel agency, Lieutenant, or a tourist guide. I am neither."

Colonel Weeks caught his shoulder as he was about to sit. "No, Barber, we want you. If you talk now, things may go easier for you."

"Things?" The fat man broke away from the colonel and dropped into a wicker chair. His wheeze was growing worse. "What sort of things do you imagine I've done?"

"It may turn out to be murder," said the colonel "Right now we've got enough to charge you with conspiracy to commit murder."

"Oh, so?" The fat man rested his palms on his knees. "Who is it I murdered, or planned to murder?"

"Me, for one," supplied Sergeant Barnum, who was leaning in the doorway. "Lemos was all ready to do me in on your orders. And maybe, though I hope not, you had Doe Love and her associate killed."

Barber fluttered his tiny eyelashes at the police lieutenant. "I'm afraid I simply don't understand any of this."

Colonel Weeks dropped both his fists down on the edge of the fat man's desk. "Try to understand this, Barber. Lemos has told us you arranged to have Gabe McClennan take over Doctor Love's flight. There hasn't been one word heard from that girl since she went down into the Veiled Lady."

Barber said, "It seems to inc I've heard of this Doctor Love; I read an informative article about her inNational Geographic or some such publication. She's a biologist, isn't she? Why on earth should I be interested in her?"

Sergeant Barnum walked across the office, straight up to Barber's desk. "Because you got it figured Doc Love was really going in after the treasure of the Veiled Lady," he said."You stuck your man Gabe with them and as soon as the treasure showed up he was supposed to let you know by radio, Only something went wrong."

"I really don't-"

"It's no use, Barber," the colonel told him. "We know you're in this up to your ears. Lemos has given us enough to put you away for a while. Your only chance now is to cooperate with us."

Barber sighed a wheezing sigh. He rested both hands on his broad chest. "Oh, very well, I'll be docile and helpful. What do you want to know?"

The colonel demanded, "What happened to Doctor Love?"

The fat man let out another sigh. "There you have me, Colonel. I know no more than you."

"Have you heard from Gabe since their copter entered the volcano?"

"Not a blessed word," said Barber. "He was supposed to contact me as soon as he could."

"Wait now," put in the stocky Sergeant Barnum. "You've got a couple of other heavies working on this job. I heard Lemos talking about them."

"He's been most valuable, hasn't he?" said the fat man. "Well, yes, as a matter of fact, I sent two more of my men to find out what had happened. Whether Gabe and the rest had died or whether that stupid spade. . . excuse me, Lieutenant,. . or whether Gabe had double-crossed me."

"Where did you send them?" asked Colonel Weeks.

"Eventually into the volcano."

"Into the Veiled Lady?"

"Yes. When I have my mind set on something, I persist."

"How did they go in?"

"By the same method employed by your Doctor Love. They used a helicopter," answered Barber. "It

cost me a good deal to hire the blasted thing."

The colonel's head was very close to Barber's. "Have they communicated with you since they entered the volcano?"

Barber inclined one fat hand toward his secret radio room. "Not one word," he said. "I was about to try them again."

"Go ahead and do it," ordered the colonel.

The café owner huffed up, made his way into the radio room. The colonel and Lieutenant Kiwanda were close behind him.

Seated again at the radio, Barber made a fresh attempt to contact Silvera and Tinn. But no word came to him out of the Veiled Lady. With a tiny smile, the fat man switched to a new frequency. "Perhaps, Colonel, you'd like to hear what your troops are up to."

From the radio speaker came the voice of a Jungle Patrol helicopter pilot. "This is Sandy, calling the Llongo station."

"We read you, Sandy. What's up?"

"The whole damn mountain it looks like. Better alert all emergency crews to be on standby. We may have to evacuate most of the Llongo country around the volcano."

"Huh? Why?"

"Because the Veiled Lady is starting to act up, buddy. It looks to me from up here like she's going to erupt."

"Good lord," said Colonel Weeks. "We've got to get out there." He spun around and ran from the hidden radio room.

Barber put his fat elbows on the table. "Well, there goes the treasure," he said as Lieutenant Kiwanda took hold of his arm.
