And then, on October sixteenth, Mason opened the door of the locked cabin. It happened quite by accident. One of the arelium-thaxide conduits broke in the Marie Galante's central passageway, and the resulting explosion grounded the central feed line of the instrument equipment. In a trice the passageway was a sheet of flame, rapidly filling with smoke from burning insulation.
Norris, of course, was in the bridge cuddy with locked doors between us and him, and now with the wiring burned through there was no way of signalling him he was wanted for an emergency. In his absence Mason took command.
That passageway ran the full length of the ship. Midway down it was the door leading to the women's lounge. The explosion had jammed that door shut, and smoke was pouring forth from under the sill. All at once one of the women rushed forward to announce hysterically that Mason's wife, Estelle, was in the lounge.
Adjoining the lounge was a small cabin which since the beginning of our voyage had remained locked. Norris had given strict orders that that cabin was not to be disturbed. We all had taken it as a matter of course that it contained various kinds of precision instruments.
Now, however, Mason realized that the only way into the lounge was by way of that locked cabin. If he used a heat blaster on the lounge door there was no telling what would happen to the woman inside.
He ripped the emergency blaster from its wall mounting, pressed it to the magnetic latch of the sealed cabin door and pressed the stud. An instant later he was leading his frightened wife, Estelle, out through the smoke.
The fire was quickly extinguished after that and the wiring spliced. Then when the others had drifted off, Mason called Brandt and me aside.
"We've been wondering for a long time what happened to Ganeth-Klae, the Martian inventor who worked with Norris to invent Indurate," he said very quietly. "Well, we don't need to wonder any more. He's in there."
Brandt and I stepped forward over the sill—and drew up short. Ganeth-Klae was there all right, but he would never trouble himself about making a voyage in a locked cabin. His rigid body was encased in a transparent block of amber-colored solidifex, the after-death preservative used by all Martians.
Both of us recognized his still features at once, and in addition his name-tattoo, required by Martian law, was clearly visible on his left forearm.
