“Why, yes,” replied the old man, “it is very pretty.”
He reached across the table and drew over Mr. Gosford's memorandum beside the will.
“You are progressive, sir,” he went on; “you write in iron-nutgall ink, just made, commercially, in this year of fifty-six by Mr. Stephens. But we write here as Marshall wrote in 'fifty-four, with logwood.”
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.
