"He is in his laboratory on the level above," replied the major-domo. "I do not know that he will want to be disturbed, though I believe that he will be anxious to see you."
He added this last with a nasty inflection that I did not like.
"I will go up to his quarters, at once," I said.
"No," said Hamas; "you will wait here. I will go to the master and ask his pleasure."
I brushed past him into the corridor. "You may come with me, if you will, Hamas," I said; "but whether you come or not, I must see Fal Sivas at once."
He grumbled at this disregard of his authority and hastened along the corridor a pace or two ahead of me.
As I passed my former quarters, I noticed that the door was open; but though I saw nothing of Zanda within, I gave the matter no thought.
We passed on up the ramp to the level above, and there Hamas, knocked on the door of Fal Sivas's apartment.
For a moment there was no answer; and I was about to enter the room when I heard Fal Sivas's voice demand querulously, "Who's there?"
"It is Hamas," replied the major-domo, "and the man, Vandor, who has returned."
"Send him in, send him in," directed Fal Sivas.
As Hamas opened the door, I brushed past him and, turning, pushed him out into the corridor. "He said, 'Send him in,'" I said. Then I closed the door in his face.
Fal Sivas had evidently come out of one of the other rooms of his suite in answer to our knock, for he stood now facing me with his hand still on the latch of a door in the opposite wall of the room, an angry frown contracting his brows.
"Where have you been?" he demanded.
Naturally, I have not been accustomed to being spoken to in the manner that Fal Sivas had adopted; and I did not relish it. I am a fighting man, not an actor; and, for a moment, I had a little difficulty in remembering that I was playing a part.
I did even go so far as to take a couple of steps toward Fal Sivas with the intention of taking him by the scruff of the neck and shaking some manners into him, but I caught myself in time; and as I paused, I could not but smile.
"Why don't you answer me?" cried Fal Sivas, "You are laughing; do you dare to laugh at me?"
"Why shouldn't I laugh at my own stupidity?" I demanded.
"Your own stupidity? I do not understand. What do you mean?"
"I took you for an intelligent man, Fal Sivas; and now I find that I was mistaken. It makes me smile."
I thought he was going to explode, but he managed to control himself. "Just what do you mean by that?" he demanded angrily.
"I mean that no intelligent man would speak to a lieutenant in the tone of voice in which you have just addressed me, no matter what he suspected, until he had thoroughly investigated. You have probably been listening to Hamas during my absence; so I am naturally condemned without a hearing."
He blinked at me for a moment and then said in a slightly more civil voice, "Well, go ahead, explain where you have been and what you have been doing."
"I have been investigating some of Ur Jan's activities," I replied, "but I have no time now to go into an explanation of that. The important thing for me to do now is to go to Gar Nal's hangar, and I do not know where it is. I have come here to you for that information."
"Why do you want to go to Gar Nal's hangar?" he demanded.
"Because I have word that Gar Nal's ship has left Zodanga on a mission in which both he And Ur Jan are connected."
This information threw Fal Sivas into a state of excitement bordering on apoplexy. "The calot!" he exclaimed, "the thief, the scoundrel; he has stolen all my ideas and now he has launched his ship ahead of mine."
"Calm yourself, Fal Sivas," I urged him. "We do not know yet that Gar Nal's ship has sailed. Tell me where he was building it, and I will go and investigate."
"Yes, yes," he exclaimed, "at once; but Vandor, do you know where Gar Nal was going? Did you find that out?"
"To Thuria, I believe," I replied.
Now, indeed, was Fal Sivas convulsed with rage. By comparison with this, his first outburst appeared almost like enthusiastic approval of his competitor for inventive laurels. He called Gar Nal every foul thing he could lay his tongue to and all his ancestors back to the original tree of life from which all animate things on Mars are supposed to have sprung.
"He is going to Thuria after the treasure!" he screamed in conclusion. "He has even stolen that idea from me."
"This is no time for lamentation, Fal Sivas," I snapped. "We are getting no place. Tell me where Gar Nal's hangar is, so that we may know definitely whether or not he has sailed."
With an effort, he gained control of himself; and then he gave me minute directions for finding Gar Nal's hangar, and even told me how I might gain entrance to it, revealing a familiarity with his enemy's stronghold which indicated that his own spies had not been idle.
As Fal Sivas concluded his directions, I thought that I heard sounds coming from the room behind him-muffled sounds-a gasp, a sob, perhaps. I could not tell.
The sounds were faint; they might have been almost anything; and now Fal Sivas crossed the room toward me and ushered me out into the corridor, a little hurriedly, I thought; but that may have been my imagination. I wondered if he, too, had heard the sounds.
"You had better go, now," he said; "and when you have discovered the truth, return at once and report to me."
On my way from the quarters of Fal Sivas, I stopped at my own to speak to Zanda; but she was not there, and I continued on to the little doorway through which I came and went from the house of Fal Sivas.
Hamas was there in the anteroom. He looked disappointed when he saw me. "You are going out?" he asked.
"Yes," I replied.
"Are you returning again tonight?"
"I expect to," I replied; "and by the way, Hamas, where is Zanda? She was not in my quarters when I stopped in."
"We thought you were not returning," explained the major-domo, "and Fal Sivas found other duties for Zanda. Tomorrow I shall have Phystal give you another slave."
"I want Zanda again," I said. "She performs her duties satisfactorily, and I prefer her."
"That is something you will have to discuss with Fal Sivas," he replied.
I passed out then into the night and gave the matter no further thought, my mind being occupied with far more important considerations.
My way led past the public house where I had left Jat Or and on into another quarter of the city. Here, without difficulty, I located the building that Fal Sivas had described.
At one side of it was a dark narrow alley. I entered this and groped my way to the far end, where I found a low wall, as Fal Sivas had explained that I would.
I paused there a moment and listened intently, but no sound came from the interior of the building. Then I vaulted easily to the top of the wall, and from there to the roof of a low annex. Across this roof appeared the end of the hangar in which Gar Nal had built his ship. I recognized it for what it was by the great doors set in the wall.
Fal Sivas had told me that through the crack between the two doors, I could see the interior of the hangar and quickly determine if the ship were still there.
But there was no light within; the hangar was completely dark, and I could see nothing as I glued an eye to the crack.
I attempted to move the doors, but they were securely locked. Then I moved cautiously along the wall in search of another opening.
About forty feet to the right of the doors, I discovered a small window some ten feet above the roof upon which I was standing. I sprang up to it and grasped the sill with my fingers and drew myself up in the hope that I might be able to see something from this vantage point.
