This is book 5 of the "Men at War" series.

This note contains spoilers for the book.

A new book in the "Men at War" series, which is the OSS novels (not to be confused with the "Brotherhood of War", which is army). Coauthored with William E. Butterworth IV, who I would guess to be his son. Ah, in fact it says so on the front flap.

It's thin; also the shape is funny (of the plot, not the package), as happens a lot lately with these. Perhaps structured around real stories a lot.

Our guys continue to be interested in getting scientists out for the Manhattan project (using such things as jet engine metallurgy as a cover), and in internecine warfare with the FBI. In this one they get involved with the Mafia, which even Dick Canidy finds morally ambiguous. But it gives them great connections in Sicily. In the end they pull out another scientist, and blow up a virus breeding station and a supply of nerve gas he hears about by coincidence at the last second. Meanwhile the Germans have infiltrated teams into the US, who start blowing things up. One team shortly blows itself up (on a train going through Norman Oklahoma), and the other is killed by the Mafia because of trying to protect a prostitute. So that's sort of self-limiting.
