here could survive a fall like that—perhaps with bruises and broken bones. But it was not Ralph's fall that killed him, was it? Tarquin, what was the mass of the capsule?"
"About ten tons."
"Perhaps a hundred times Ralph's mass. And so—in the peculiar conditions of the Inertial Adjustor—it fell to the floor a hundred times faster than Ralph."
And then, in a flash, I saw it all. Unlike my friendly lift cabin of Wells's analogy, the capsule would drive rapidly to the floor, engulfing Ralph. My unwelcome imagination ran away with the point: I saw the complex ceiling of the capsule smashing into Ralph's staring face, a fraction of a second before the careening metal hit his body and he burst like a balloon . . .
Tarquin buried his eyes in the palm of his hand. "I live with the image. Why are you telling me this?"
For answer, Holmes turned to Wells. "Mr Wells, let us test your own powers of observation. What is the single most startling aspect of the case?"
He frowned. "When we first visited the Inertial Adjustor chamber with Tarquin, I recall looking into the capsule, and scanning the floor and couch for signs of Ralph's death."
"But," Holmes said, "the evidence of Ralph's demise—bizarre, grotesque—were fixed to the ceiling, not the floor."
"Yes. Tarquin told me to look up—just as later, now I think on it, you, Mr Holmes, had to tell the engineer Bryson to raise his head, and his face twisted in horror." He studied Holmes. "So, a breaking of the symmetry at last. Tarquin knew where to look; Bryson did not. What does that tell us?"
Holmes said, "By looking down, by seeking traces of Ralph on the couch, the floor, we demonstrated we had not understood what had happened to Ralph. We had to be shown—as had Bryson! If Bryson had sought to murder Ralph he would have chosen some other method. Only someone who has studied the properties of a gravity field changed by the Inertial Adjustor would know immediately how cutting that cable would kill Ralph."
Tarquin sat very still, eyes covered. "Someone like me, you mean?"
Wells said, "Is that an admission, Tarquin?"
Tarquin lifted his face to Holmes, looking thoughtful. "You do not have any proof. And there is a counter-argument. Bryson could have stopped me, before I cut through the cable. The fact that he did not is evidence of his guilt!"
"But he was not there," Holmes said evenly. "As you arranged."
Tarquin guffawed. "He was taking breakfast with my sister-in-law! How could I arrange such a thing?"
"There is the matter of Bryson's breakfast egg, which took unusually long to cook," Holmes said.
"Your egg again, Holmes!" Wells cried.
"On that morning," said Holmes, "and that morning alone, you, Mr Brimicombe, collected fresh eggs from the coop. I checked with the housekeeper. The eggs used for breakfast here are customarily a day or more old. As you surely learned as a child fond of the hens, Tarquin, a fresh egg takes appreciably longer to cook than one that is a day or more old. A fresh egg has a volume of clear albumen solution trapped in layers of dense egg white around the yolk. These layers make the egg sit up in the frying pan. After some days the albumen layers degenerate, and the more watery egg will flatten out, and is more easily cooked."
Wells gasped. "My word, Holmes. Is there no limit to your intelligence?"
"Oh," said Brimicombe, "but this is—"
"Mr Brimicombe," Holmes said steadily, "you are not a habitual criminal. When I call in the police they will find all the proof any court in the land could require. Do you doubt that?"
Tarquin Brimicombe considered for a while, and then said: "Perhaps not." He gave Holmes a grin, like a good loser on the playing field. "Maybe I tried to be too clever; I thought I was home clear anyway, but when I knew you were coming I decided to bluff you over Bryson to be sure. I knew about his involvement with Jane; I knew he would have a motive for you to pick up—"
"And so you tried to implicate an innocent man." I could see Holmes's cool anger building.
Wells said, "So it is resolved. Tell me one thing. Tarquin. If not for your brother's money, why?"
He showed surprise. "Do you not know, Bertie? The first aviator will be the most famous man in history. I wanted to be that man, to fly Ralph's craft into the air, perhaps even to other worlds."
"But," Wells said, "Ralph
