Elijah Bailey's third and final documented stressful and career making/breaking romp with R. Daneel Olivaw.

In Asimov's efforts to tie his robot stories together with his Foundation universe, some changes are made to the basic format of this book as opposed to the other two Bailey/Olivaw books. For one thing, Daneel takes a bit of a back seat to a new robot, named Giskard (who it seems will become something of a lynch pin in the times to come).

This time, the stakes are higher than ever before - and yet, the mystery to be solved has very little bearing on those stakes.

It almost feels like the plot got away from Asimov toward the end, and he fails to bring it back in line.
