eleven o'clock
After half-an-hour I left , and more puzzled than ever , returned to the house in Richmond Road . Sometimes I felt entirely convinced that my love was authoress of the foul deed ; yet at others there seemed something wanting in the confirmation of my suspicions . Regarding the latter I could not overlook the fact that Short had told a story which was false on the face of it , while the utter absence of any motive on my love 's part in murdering the old gentleman seemed to point in an entirely opposite direction . Dr. Diplock , the coroner , had fixed the inquest for eleven o'clock on the morrow ; therefore I assisted Dr. Farmer , of Kew , the police surgeon , to make the post-mortem . We made the examination in the afternoon , before the light faded , and if the circumstances of the crime were mysterious , the means by which the unfortunate man was murdered were , we found , doubly so . Outwardly , the wound was an ordinary one , one inch in breadth , inflicted by a blow delivered from left to right . The weapon had entered between the fourth and fifth ribs , and the heart had been completely transfixed by some sharp cutting instrument .
