We walked the last half-mile to the field. The afternoon's heat lingered even in the shade of the hedgerows. Birds chirped and rustled the branches.
"Well, Robert," I said, "you'll have the chance to observe Mr. Holmes in action, and he can hear your story in your own words instead of mine. Holmes, Robert is a great enthusiast of your stories."
"I am flattered," Holmes said, "though of course the credit goes entirely to you, Watson, and to your craft."
We had no more opportunity to chat, for we reached the newly patterned field. Robert's children--including Little Robbie, who was considerably taller and larger than his father-- had arrived before us, despite our use of the motorcar. They stood in order of descending height on the bottom rail of the fence, exclaiming over the pattern crushed into the grain.
Sir Arthur made as if to plunge into the very center of the new theorem, but Holmes clasped him by the shoulder.
"Stay back!" Holmes cried. "Robert! To the lane! Keep away the spectators!"
"Very well, Mr. Holmes." Robert and his children tramped away down the path.
I marveled at the efficiency of the country grapevine, to give everyone such quick notice of the new field theorem.
Holmes plunged past Sir Arthur. But instead of forging into the field, he climbed the fence and balanced atop the highest rail to gaze across the waving grain. He traced with his eyes the valleys and gulches etched into the surface. Only after some minutes, and a complete circumnavigation of the field, did he venture into the field theorem itself.
Sir Arthur observed Holmes's method.
"You see, John?" Sir Arthur said. "Even your Mr. Holmes acknowledges the power-- the danger-present here."
"Sir Arthur," I said in the mildest tone possible, "why should danger result, if the communication is from those who loved you, in another life?"
"Why..." he said, momentarily awkward, "John, you'll understand after the seance tonight. The other side is... different."
Robert ran down the path, panting.
"I'm sorry, Mr. Holmes, Sir Arthur," he said. "We kept them away as long as we could. Constable Brown ordered us to stand aside."
"More devotion to duty than to sense," Sir Arthur muttered. He sighed. "I'm sure you did your best," said he to Robert.
A group of curious people, led by Constable Brown and minimally constrained by Robert's children, approached between the hedgerows. Holmes was right: Someone, somehow, had alerted the public. Sightseers who had come to see the other field theorem now found themselves doubly fortunate.
The constable entered the field just as Holmes left it. The sightseers crowded up to the fence to view the new theorem.
Holmes rejoined Sir Arthur and myself.
"I have seen what I needed," Holmes said. "It's of no matter to me if the tourists trample the fields."
"But we must survey the theorem!" Sir Arthur said. "We still do not know its meaning!" He ordered Robert to do his best to prevent the sightseers from marring the designs.
"If we depart now," Holmes said, "before the constable realizes he is baffled by the phenomenon, we will be spared interrogation."
Dinner being far preferable to interrogation, we took Holmes's advice. I noticed, to my amusement, that Robert's children had lined the spectators up. Some visitors even offered the boys tips, or perhaps entry fees. At least the family would not count its day an utter loss.
A photographer lowered his heavy camera from his shoulder. He set it up on its tripod and disappeared beneath the black shadow-cloth to focus the lenses. He exposed a plate, setting off a great explosion of flash powder. Smoke billowed up, bitter and sulfurous.
The journalists began to question Constable Brown, who puffed himself up with importance and replied to their questions. We hurried away, before the journalists should recognize Sir Arthur-- or Holmes-- and further delay us.
"If the motor starts," Sir Arthur said, "we will be in time for the seance."
For a moment I wondered if Holmes would turn volte face, return to the field, and submit to questioning by Constable Brown and the journalists, in preference to submitting to the seance.
To our surprise, the motorcar started without hesitation. As Sir Arthur drove down the lane, Holmes puzzled over something in his hands.
"What is that, Holmes?"
"Just a bit of wood, a stake," Holmes said, putting it in his pocket. "I found it in the field."
As he was not inclined to discuss it further, we both fell silent. I wondered if we had to contend with--besides the field theorems, the ghostly lights, and the seance-- with wooden stakes and vampires.
"Tell me, Sir Arthur," Holmes said over the rhythmic cough of the motor, "are any of your spirits known to live on Mars?"
"Mars?" Sir Arthur exclaimed. "Mars! I don't believe I've ever heard one mention it. But I don't believe I've ever heard one asked." He turned to Holmes, his eyes bright with anticipation. "We shall ask, this very evening! Why, that would explain Professor Schiaparelli's 'canali,' would it not?"
"Perhaps," Holmes said. "Though I fail to understand what use channels would be-- to dead people."
Darkness gathered as we motored down the rough lane. Sir Arthur turned on the headlamps of the autocar, and the beams pierced the dimness, casting eerie shadows and picking out the twisted branches of trees. The wind in our face was cool and pleasant, if tinged somewhat by the scent of petrol.
The engine of the autocar died, and with it the light from the headlamps.
Sir Arthur uttered another of his exotic curses.
"I suppose it will be of no use," he said, "but would one of you gentlemen kindly try the crank?"
Holmes-- knowing of my shoulder, shattered by a Jezail bullet in Afghanistan and never quite right since-- leapt from the passenger seat and strode to the front of the automobile. He cranked it several times, to no avail. Without a word, he unstrapped the engine cover and opened it.
"It's too dark, Mr. Holmes," Sir Arthur said. "We'll have to walk home from here."
"Perhaps not, Sir Arthur," said I. "Holmes's vision is acute." I climbed down, as well, to see if I could
be of any assistance. I wished the automobile carried a kerosene lamp, though I suppose I would have had to hold it too far away from the engine, and the petrol tank, for it to be of much use.
"Can you see the difficulty, Holmes?" I asked.
His long fingers probed among the machined parts of the engine.
"Difficulty, Watson?" he said. "There is no difficulty here. Only enterprising cleverness."
The automobile rocked, and I assumed Sir Arthur was getting down to join us and try to help with the repairs.
"Cleverness?" said I. "Surely you can't mean-- Ah!" Light flickered across his hawkish face, and for a moment I thought he had repaired the engine and the headlamps. Then I thought that Sir Arthur must have an innovative automobile, in which the headlamps gained their power from an independent battery rather than from the workings of the motor.
But then, I thought, they would surely not have failed at the same moment as the motor.
And finally I realized that the headlamps were dark, the engine still, and the lights on Holmes's face emanated from a separate source entirely.
I raised my eyes in the direction of the flickering lights. An eerie radiance lit the forest beyond the road. As I watched, it descended slowly beneath the tops of the trees.
"Sir Arthur!" I cried.
His silhouette moved quickly toward the mysterious lights.
Holmes and I ran after him. I felt a shiver, whether of fear or of unearthly chill, I could not have said.
Suddenly a great flash of light engulfed us, and a great shock of sound. Dazzled, I stumbled and fell, crying, "Sir Arthur!" I thought I heard one of Sir Arthur's exotic oaths, this time in the voice of Sherlock Holmes.
