From the beginning this story feels reminiscent of "The Street", and not in a good way. Although the three criminals are referred to as "Messrs" and "gentlemen", which is somewhat respectful, their names clearly suggest immigrant families, even before this is made clear later, and the association with them of crime is uncomfortable to this modern reader. I'm also guessing I'm supposed to side with the "Terrible Old Man", but I'm not exactly feeling that sentiment at the moment.
I do like that it's set in Kingsport though - an area I'd like to read more about, and don't feel is nearly as well developed in Lovecraft's fiction as other locations such as Arkham and, of course, Providence. Though even this setting is scant here. I'm also intrigued by the seemingly sentient lead bottles and pendulums inside them. But the writing seems to be often laboured, and repetitive, and I'm thinking this story could be told in a much shorter version, even though it's already very short. Or not told at all.
The ending is predictable, and I found it disappointing. After a repetitive and padded build it didn't deliver the goods for me, and the story just died away. I do not recommend this story, on almost any grounds.
