Now, if the prosecutor will be so kind as to let me see that note - thank you, sir.This is the identical note.You have all heard the various theories of the jar and have read the note.Here it is in plain, cold black and white - in Dr.Dixon's own handwriting, as you know, and reads: 'This will cure your headache.Dr.Dixon.'"Alma Willard seemed as one paralysed.Was Kennedy, who had been engaged by her father to defend her fianc=82, about to convict him?
Before we draw the final conclusion," continued Kennedy gravely, "there are one or two points I wish to elaborate.Walter, will you open that door into the main hall?"I did so, and two policemen stepped in with a prisoner.It was Thurston, but changed almost beyond recognition.His clothes were worn, his beard shaved off, and he had a generally hunted appearance.
Thurston was visibly nervous.Apparently he had heard all that Kennedy had said and intended he should hear, for as he entered he almost broke away from the police officers in his eagerness to speak.
"Before God," he cried dramatically, "I am as innocent as you are of this crime, Professor Kennedy.""Are you prepared to swear before me," almost shouted Kennedy, his eyes blazing, "that you were never served properly by your wife's lawyers in that suit?"The man cringed back as if a stinging blow had been delivered between his eyes.As he met Craig's fixed glare he knew there was no hope.Slowly, as if the words were being wrung from him syllable by syllable, he said in a muffled voice:
"No, I perjured myself.I was served in that suit.But - ""And you swore falsely before Kimmel that you were not?" persisted Kennedy.
"Yes," he murmured."But - "
"And you are prepared now to make another affidavit to that effect?""Yes," he replied."If - "
"No buts or ifs, Thurston," cried Kennedy sarcastically."What did you make that affidavit for? What is your story?""Kimmel sent for me.I did not go to him.He offered to pay my debts if I would swear to such a statement.I did not ask why or for whom.I swore to it and gave him a list of my creditors.Iwaited until they were paid.Then my conscience - " I could not help revolting at the thought of conscience in such a wretch, and the word itself seemed to stick in his throat as he went on and saw how feeble an impression he was ****** on us - " my conscience began to trouble me.I determined to see Vera, tell her all, and find out whether it was she who wanted this statement.I saw her.
When at last I told her, she scorned me.I can confirm that, for as I left a man entered.I now knew how grossly I had sinned, in listening to Mose Kimmel.I fled.I disappeared in Maine.Itravelled.Every day my money grew less.At last I was overtaken, captured, and brought back here."He stopped and sank wretchedly down in a chair and covered his face with his hands.
"A likely story," muttered Leland in my ear.
Kennedy was working quickly.Motioning the officers to be seated by Thurston, he uncovered a jar which he had placed on the table.
The colour had now appeared in Alma's cheeks, as if hope had again sprung in her heart, and I fancied that Halsey Post saw his claim on her favour declining correspondingly.
"I want you to examine the letters in this case with me," continued Kennedy."Take the letter which I read from Miss Lytton, which was found following the strange disappearance of the note from Thurston."He dipped a pen into a little bottle, and wrote on a piece of paper:
What is your opinion about Cross's Headache Cure? Would you recommend it for a nervous headache?
BURGESS THURSTON, c/o Mrs.S.BONCOUR.
Craig held up the writing so that we could all see that he had written what Dixon declared Thurston wrote in the note that had disappeared.Then he dipped another pen into a second bottle, and for some time he scrawled on another sheet of paper.He held it up, but it was still perfectly blank.
"Now," he added, "I am going to give a little demonstration which I expect to be successful only in a measure.Here in the open sunshine by this window I am going to place these two sheets of paper side by side.It will take longer than I care to wait to make my demonstration complete, but I can do enough to convince you."For a quarter of an hour we sat in silence, wondering what he would do next.At last he beckoned us over to the window.As we approached he said, "On sheet number one I have written with quinoline; on sheet number two I wrote with a solution of nitrate of silver."We bent over.The writing signed "Thurston" on sheet number one was faint, almost imperceptible, but on paper number two, in black letters, appeared what Kennedy had written: " Dear Harris: Since we agreed to disagree we have at least been good friends.""It is like the start of the substituted letter, and the other is like the missing note," gasped Leland in a daze.
"Yes," said Kennedy quickly."Leland, no one entered your office.
No one stole the Thurston note.No one substituted the Lytton letter.According to your own story, you took them out of the safe and left them in the sunlight all day.The process that had been started earlier in ordinary light, slowly, was now quickly completed.In other words, there was writing which would soon fade away on one side of the paper and writing which was invisible but would soon appear on the other.
"For instance, quinoline rapidly disappears in sunlight.Starch with a slight trace of iodine writes a light blue, which disappears in air.It was something like that used in the Thurston letter.
