After breakfast I improvised a dark room and developed the films, while Craig went down the back lane along the shore "looking for clues," as he said briefly.Toward noon he returned, and I could see that he was in a brown study.So I said nothing, but handed him the photographs of the road.He took them and laid them down in a long line on the library floor.They seemed to consist of little ridges of dirt on either side of a series of regular round spots, some of the spots very clear and distinct on the sides, others quite obscure in the centre.Now and then where you would expect to see one of the spots, just for the symmetry of the thing, it was missing.As I looked at the line of photographs on the floor I saw that they were a photograph of the track made by the tire of an automobile, and I suddenly recalled what the gardener had said.
Next Craig produced the results of his morning's work, which consisted of several dozen sheets of white paper, carefully separated into three bundles.These he also laid down in long lines on the floor, each package in a separate line.Then I began to realise what he was doing, and became fascinated in watching him on his hands and knees eagerly scanning the papers and comparing them with the photographs.At last he gathered up two of the sets of papers very decisively and threw them away.Then he shifted the third set a bit, and laid it closely parallel to the photographs.
"Look at these, Walter," he said."Now take this deep and sharp indentation.Well, there's a corresponding one in the photograph.
So you can pick them out one for another.Now here's one missing altogether on the paper.So it is in the photograph."Almost like a schoolboy in his glee, he was comparing the little round circles made by the metal insertions in an "anti-skid"automobile tire.Time and again I had seen imprints like that left in the dust and grease of an asphalted street or the mud of a road.It had never occurred to me that they might be used in any way.Yet here Craig was, calmly tracing out the similarity before my very eyes, identifying the marks made in the photograph with the prints left on the bits of paper.
As I followed him, I had a most curious feeling of admiration for his genius."Craig," I cried, "that's the thumb-print of an automobile.""There speaks the yellow journalist," he answered merrily.
"'Thumb Print System Applied to Motor Cars'--I can see the Sunday feature story you have in your mind with that headline already.
Yes, Walter, that's precisely what this is.The Berlin police have used it a number of times with the most startling results.""But, Craig," I exclaimed suddenly, "the paper prints, where did you get them? What machine is it?""It's one not very far from here," he answered sententiously, and I saw he would say nothing more that might fix a false suspicion on anyone.Still, my curiosity was so great that if there had been an opportunity I certainly should have tried out his plan on all the cars in the Fletcher garage.
Kennedy would say nothing more, and we ate our luncheon in silence.Fletcher, who had decided to lunch with the Greenes, called Kennedy up on the telephone to tell him it would be all right for him to call on Miss Bond later in the afternoon.
"And I may bring over the apparatus I once described to you to determine just what her nervous condition is?" he asked.
Apparently the answer was yes, for Kennedy hung up the receiver with a satisfied, "Good-bye.""Walter, I want you to come along with me this afternoon as my assistant.Remember I'm now Dr.Kennedy, the nerve specialist, and you are Dr.Jameson, my colleague, and we are to be in consultation on a most important case.""Do you think that's fair?" I asked hotly, "to take that girl off her guard, to insinuate yourself into her confidence as a medical adviser, and worm out of her some find of fact incriminating someone? I suppose that's your plan, and I don't like the ethics, or rather the lack of ethics, of the thing.""Now think a minute, Walter.Perhaps I am wrong; I don't know.
Certainly I feel that the end will justify the means.I have an idea that I can get from Miss Bond the only clue that I need, one that will lead straight to the criminal.Who knows? I have a suspicion that the thing I'm going to do is the highest form of your so-called ethics.If what Fletcher tells us is true that girl is going insane over this thing.Why should she be so shocked over the death of an uncle she did not live with? I tell you she knows something about this case that it is necessary for us to know, too.If she doesn't tell someone, it will eat her mind out.I'll add a dinner to the box of cigars we have already bet on this case that what I'm going to do is for the best--for her best."Again I yielded, for I was coming to have more and more faith in the old Kennedy I had seen made over into a first-class detective, and together we started for the Greenes', Craig carrying something in one of those long black handbags which physicians use.
Fletcher met us on the driveway.He seemed to be very much affected, for his face was drawn, and he shifted from one position to another nervously, from which we inferred that Miss Bond was feeling worse.It was late afternoon, almost verging on twilight, as he led us through the reception-hall and thence onto a long porch overlooking the bay and redolent with honeysuckle.
Miss Bond was half reclining in a wicker chair us we entered.She started to rise to greet us, but Fletcher gently restrained her, saying, as he introduced us, that he guessed the doctors would pardon any informality from an invalid.
