Granice went on, ashamed of his outburst.  “It was simple enough, as you’ll see.  From the day the old man said to me, ’Those Italians would murder you for a quarter,’ I dropped everything and just worked at my scheme.  It struck me at once that I must find a way of getting to Wrenfield and back in a night—­and that led to the idea of a motor.  A motor—­that never occurred to you?  You wonder where I got the money, I suppose.  Well, I had a thousand or so put by, and I nosed around till I found what I wanted—­a second-hand racer.  I knew how to drive a car, and I tried the thing and found it was all right.  Times were bad, and I bought it for my price, and stored it away.  Where?  Why, in one of those no-questions-asked garages where they keep motors that are not for family use.  I had a lively cousin who had put me up to that dodge, and I looked about till I found a queer hole where they took in my car like a baby in a foundling asylum...  Then I practiced running to Wrenfield and back in a night.  I knew the way pretty well, for I’d done it often with the same lively cousin—­and in the small hours, too.  The distance is over ninety miles, and on the third trial I did it under two hours.  But my arms were so lame that I could hardly get dressed the next morning...

“Well, then came the report about the Italian’s threats, and I saw I must act at once...  I meant to break into the old man’s room, shoot him, and get away again.  It was a big risk, but I thought I could manage it.  Then we heard that he was ill—­that there’d been a consultation.  Perhaps the fates were going to do it for me!  Good Lord, if that could only be! ...”

Granice stopped and wiped his forehead:  the open window did not seem to have cooled the room.

“Then came word that he was better; and the day after, when I came up from my office, I found Kate laughing over the news that he was to try a bit of melon.  The house-keeper had just telephoned her—­all Wrenfield was in a flutter.  The doctor himself had picked out the melon, one of the little French ones that are hardly bigger than a large tomato—­and the patient was to eat it at his breakfast the next morning.

“In a flash I saw my chance.  It was a bare chance, no more.  But I knew the ways of the house—­I was sure the melon would be brought in over night and put in the pantry ice-box.  If there were only one melon in the ice-box I could be fairly sure it was the one I wanted.  Melons didn’t lie around loose in that house—­every one was known, numbered, catalogued.  The old man was beset by the dread that the servants would eat them, and he took a hundred mean precautions to prevent it.  Yes, I felt pretty sure of my melon ... and poisoning was much safer than shooting.  It would have been the devil and all to get into the old man’s bedroom without his rousing the house; but I ought to be able to break into the pantry without much trouble.
