Now -- me? I’ve had some pretty tough cases in my time. But few have reached the complexity of the assassination/heist documented by my trusty drinking-buddy Dr Justice, here:
Dr J isn’t really as dumb as he looks, but he does seem to have missed the key point here. Why photoshop-off the picture of the wristwatch? Obviously so that those investigating the assassination, having access only to the photoshopped version of the fatal session in the locked room, would not realize that the patriarch had been wearing a wristwatch before his demise -- and which, afterwards, was not found on the corpse. So that the assumption would be that the motive was personal, or for religious rivalry, or perhaps just some atheist that hated the Church. No-one would ever guess that the crime was committed to make away with the hidden contents of the watch.
Pretty neat, in theory: but the criminal’s failure to shop-off the tabletop reflection of the stolen item provided the key to the whole case.
