This is the second entry in the series about Randolph, the intelligent Lab. This entry has Randolph hobnobbing with low-level diplomats (and spies!!) at the UN. Again, the "main" mystery is tied up with Imogen's disappearance, and in the process of solving the various murders, we learn more about Imogen.
I continue to love these characters and to truly enjoy the leisurely way Englert constructs his stories. In this hustle-bustle life, it's really enjoyable to slow down with a good book. I look forward to Randolph's further adventures.
