He ticked the items off on his fingers.
"A mysterious man who entered the garden one night and left his footprints in the gravel, and whose visit had a strange and mysterious effect on Rattar. Funny feelings produced in the bosom of the housemaid by the presence of her master. Doors of unused rooms mysteriously locked and keys taken away; said to be old papers inside. Mysterious visit of mysterious man at dead of night to remove the said papers. A ring that couldn't come off the owner's finger mysteriously lost. Mysterious burglary on night of the murder by mysterious burglar who left all windows and doors locked behind him and took nothing away. Mysterious perambulations of his garden every night at nine o'clock by Mr. Simon Rattar."
"Great Scot!" murmured Cromarty.
"I have given you the items in what turned out to be their order of date, but I got them higgledy-piggledy and served up in a sauce of mystery and trembly sensations that left me utterly flummoxed as to how much—if anything—was sober fact. However, I began by fastening on to two things. The first was the burglary, which of course at once suggested the possibility that the man who had committed the crime at Keldale had returned to Rattar's house and got in by that window. The second was the nightly perambulations, which could easily be tested. When Mr. Rattar emerged at nine that night, I was in the garden before him. And what do you think he did?"
"Had a look at his brother's grave?"
"Smoked two pipes of tobacco! A man who was an anti-tobacco fanatic! The truth hit me straight in the eye—'That man is not Simon Rattar!' And then of course everything dropped into its place. The ex-convict twin brother, the only evidence of whose supposititious death was an announcement in the paper, obviously put in as a blind. The personal resemblance between the two. All the yarns told me by the housemaid, including the strange visitor—George of course arriving; the man who came for the papers—George himself taking out the body; and the vanished ring. Everything fitted in now, and the correspondence between Sir Reginald and Rattar which had beaten me before, gave the clue at once as to motive."
"I guess you felt you had deserved a drink that trip!" said Ned.
"I didn't stop to have my drink. I went straight off to see old Ison and pumped him for the rest of the evening. He wasn't very helpful but everything I could get out of him went to confirm my theory. I found for certain that Simon Rattar had never smoked in his life, and that George used to be a heavy smoker. I also learned that a few recent peculiarities of conduct had struck the not too observant Ison, one being very suggestive. Rattar, it seemed, kept an old pair of kid gloves in his desk which he was in the habit of wearing when he was alone in the office."
"Don't quite see the bearing of that."
