This is an ordinary , although an atrocious instance of crime. There is nothing peculiarly outré about it. You will observe that, for this reason, the mystery has been considered easy, when, for this reason, it should have been considered difficult, of solution. Thus, at first, it was thought unnecessary to offer a reward. The myrmidons of G—— were able at once to comprehend how and why such an atrocity might have been committed.
