Ras Thavas awakened from the anaesthetic a new and gorgeous creature- a youth of such wondrous beauty that he seemed of heavenly rather than worldly origin; but in that beautiful head was the hard, cold, thousand-year-old brain of the master surgeon. As he opened his eyes he looked upon me coldly.

"You have done well," he said.

"What I have done, I have done for friendship-perhaps for love," I said, "so you can thank the sentimentalism you decry for the success of the transfer."

He made no reply.

"And now," I continued, "I shall look to you for the fulfilment of the promise you have made me."

"When you bring Xaxa's body I shall transfer to it the brain of any of my subjects you may select," he said, "but were I you, I would not risk my life in such an impossible venture-you cannot succeed. Select another body-there are many beautiful ones-and I will give it the brain of 4296-E-2631-H.

"None other than the body now owned by the Jeddara Xaxa will fulfill your promise to me," I said.

He shrugged and there was a cold smile upon his handsome lips. "Very well," he said, "fetch Xaxa. When do you start?"

"I am not yet ready. I will let you know when I am."

"Good and now begone-but wait! First go to the office and see what cases await us and if there be any that do not require my personal attention, and they fall within your skill and knowledge, attend to them yourself."

As I left him I noticed a crafty smile of satisfaction upon his lips. What had aroused that? I did not like it and as I walked away I tried to conjure what could possibly have passed through that wondrous brain to call forth at that particular instant so unpleasant a smile. As I passed through the doorway and into the corridor beyond I heard him summon his personal slave and body servant, Yamdor, a huge fellow whose loyalty he kept through the bestowal of lavish gifts and countless favors. So great was the fellow's power that all feared him, as a word to the master from the lips of Yamdor might easily send any of the numerous slaves or attendants to an ersite slab for eternity. It was rumored that he was the result of an unnatural experiment which had combined the brain of a woman with the body of a man, and there was much in his actions and mannerisms to justify this general belief. His touch, when he worked about his master, was soft and light, his movements graceful, his ways gentle, but his mind was jealous, vindictive and unforgiving.

I believe that he did not like me, through jealousy of the authority I had attained in the establishment of Ras Thavas; for there was no questioning the fact that I was a lieutenant, while he was but a slave; yet he always accorded me the utmost respect. He was, however, merely a minor cog in the machinery of the great institution presided over by the sovereign mind of Ras Thavas, and as such I had given him little consideration; nor did I now as I bent my steps towards the office.

I had gone but a short distance when I recalled a matter of importance upon which it was necessary for me to obtain instructions from Ras Thavas immediately; and so I wheeled about and retraced my way towards his apartments, through the open doorway of which, as I approached, I heard the new voice of the master surgeon. Ras Thavas had always spoken in rather loud tones, whether as a vocal reflection of his naturally domineering and authoritative character, or because of his deafness, I do not know; and now, with the fresh young vocal cords of his new body, his words rang out clearly and distinctly in the corridor leading to his room.

"You will, therefore, Yamdor," he was saying, "go at once and, selecting two slaves in whose silence and discretion you may trust, take the subject from the apartments of Vad Varo and destroy it-let no vestige of body or brain remain. Immediately after, you will bring the two slaves to the laboratory F-30-L, permitting them to speak to no one, and I will consign them to silence and forgetfulness for eternity. Vad Varo will discover the absence of the subject and report the matter to me."

"During my investigation you will confess that you aided 4296-E-2631-H to escape, but that you have no idea where it intended going. I will sentence you to death as punishment, but at last explaining how urgently I need your services and upon your solemn promise never to transgress again, I will defer punishment for the term of your continued good behaviour. Do you thoroughly understand the entire plan?"

"Yes, master," replied Yamdor.

"Then depart at once and select the slaves who are to assist you."

Quickly and silently I sped along the corridor until the first intersection permitted me to place myself out of sight of anyone coming from Ras Thavas' apartment; then I went directly to the chamber occupied by Valla Dia. Unlocking the door I threw it open and beckoned her to come out. "Quick! Valla Dia!" I cried. "No time is to be lost. In attempting to save you I have but brought destruction upon you. First we must find a hiding place for you, and that at once- afterwards we can plan for the future."

The place that first occurred to me as affording adequate concealment was the half forgotten vaults in the pits beneath the laboratories, and towards these I hastened Valla Dia. As we proceeded I narrated all that had transpired, nor did she once reproach me; but, instead, expressed naught but gratitude for what she was pleased to designate as my unselfish friendship. That it had miscarried, she assured me, was no reflection upon me and she insisted that she would rather die in the knowledge that she possessed one such friend than to live on indefinitely, friendless.

We came at last to the chamber I sought-vault L-42-X, in building 4-J-21, where reposed the bodies of the ape and the man, each of which possessed half the brain of the other. Here I was forced to leave Valla Dia for the time, that I might hasten to the office and perform the duties imposed upon me by Ras Thavas, lest his suspicions be aroused when Yamdor reported that he had found her apartment vacant.

I reached the office without it being discovered by anyone who might report the fact to Ras Thavas that I had been a long time coming from his apartment. To my relief, I found there were no cases. Without appearing in any undue haste, I nevertheless soon found an excuse to depart and at once made my way towards my own quarters, moving in a leisurely and unconcerned manner and humming, as was my wont (a habit which greatly irritated Ras Thavas), snatches from some song that had been popular at the time that I quit Earth. In this instance it was "Oh, Frenchy."

I was thus engaged when I met Yamdor moving hurriedly along the corridor leading from my apartment, in company with two male slaves. I greeted him pleasantly, as was my custom, and he returned my greeting; but there was an expression of fear and suspicion in his eyes. I went at once to my quarters, opened the door leading to the chamber formerly occupied by Valla Dia and then hastened immediately to the apartment of Ras Thavas, where I found him conversing with Yamdor. I rushed in apparently breathless and simulating great excitement.

"Ras Thavas," I demanded, "what have you done with 4296-E-2631-H? She has disappeared; her apartment is empty; and as I was approaching it I met Yamdor and two other slaves coming from that direction." I turned then upon Yamdor and pointed an accusing finger at him. "Yamdor!" I cried. "What have you done with this woman?"

Both Ras Thavas and Yamdor seemed genuinely puzzled and I congratulated myself that I had thus readily thrown them off the track. The master surgeon declared that he would make an immediate investigation; and he at once ordered a thorough search of the ground and of the island outside the enclosure. Yamdor denied any knowledge of the woman and I, at least, was aware of the sincerity of his protestations, but not so Ras Thavas. I could see a hint of suspicion in his eyes as he questioned his body servant; but evidently he could conjure no motive for any such treasonable action on the part of Yamdor as would have been represented by the abduction of the woman and the consequent gross disobedience of orders.
