Part 39

He turned and fumbled in his little case of bottles.

“I carry a bit of acid for my people's indigestions. It has other uses.” He whipped out the stopper of his vial and dabbed Gosford's notes and Marshall's signature.

“See!” he cried. “Your writing is blue, Mr. Gosford, and Marshall's red!”

With an oath the trapped man struck at Gaeki's hand. The vial fell and cracked on the table. The hydrochloric acid spread out over Marshall's will. And under the chemical reagent the figure in the bequest of fifty thousand dollars changed beautifully; the bar of the 5 turned blue, and the remainder of it a deep purple-red like the body of the will.

“Gaeki,” cried my father, “you have trapped a rogue!”

“And I have lost a measure of good acid,” replied the old man. And he began to gather up the bits of his broken bottle from the table.

VIII. The Hole in the Mahogany Panel

Sir Henry paused a moment, his finger between the pages of the ancient diary.

“It is the inspirational quality in these cases,” he said, “that impresses me. It is very nearly absent in our modern methods of criminal investigation. We depend now on a certain formal routine. I rarely find a man in the whole of Scotland Yard with a trace of intuitive impulse to lead him.... Observe how this old justice in Virginia bridged the gaps between his incidents.”

He paused.

“We call it the inspirational instinct, in criminal investigation ... genius, is the right word.”

He looked up at the clock.

“We have an hour, yet, before the opera will be worth hearing; listen to this final case.”

The narrative of the diary follows:

The girl was walking in the road. Her frock was covered with dust. Her arms hung limp. Her face with the great eyes and the exquisite mouth was the chalk face of a ghost. She walked with the terrible stiffened celerity of a human creature when it is trapped and ruined.

Night was coming on. Behind the girl sat the great old house at the end of a long lane of ancient poplars.

This was a strange scene my father came on. He pulled up his big red-roan horse at the crossroads, where the long lane entered the turnpike, and looked at the stiff, tragic figure. He rode home from a sitting of the county justices, alone, at peace, on this midsummer night, and God sent this tragic thing to meet him.

He got down and stood under the crossroads signboard beside his horse.

The earth was dry; in dust. The dead grass and the dead leaves made a sere, yellow world. It looked like a land of unending summer, but a breath of chill came out of the hollows with the sunset.

The girl would have gone on, oblivious. But my father went down into the road and took her by the arm. She stopped when she saw who it was, and spoke in the dead, uninflected voice of a person in extremity.

“Is the thing a lie?” she said.

“What thing, child?” replied my father.

“The thing he told me!”

“Dillworth?” said my father. “Do you mean Hambleton Dillworth?”

The girl put out her free arm in a stiff, circling gesture. “In all the world,” she said, “is there any other man who would have told me?”

My father's face hardened as if of metal. “What did he tell you?”

The girl spoke plainly, frankly, in her dead voice, without equivocation, with no choice of words to soften what she said:

“He said that my father was not dead; that I was the daughter of a thief; that what I believed about my father was all made up to save the family name; that the truth was my father robbed him, stole his best horse and left the country when I was a baby. He said I was a burden on him, a pensioner, a drone; and to go and seek my father.”
