An Affair of Honor — Robert N. Macomber

At the beginning of this fifth novel in Robert N. Macomber's award-winning Honor series, it is December 1873 and Lt. Peter Wake is the executive officer of the USS Omaha on dreary patrol in the West Indies. Lonely for his family, he is looking forward to returning home to Pensacola in a few months and rekindling his troubled marriage with Linda. But fate has other plans for Wake. He runs afoul of the Royal Navy in Antigua and a beautiful French woman enters his life in Martinique. Then he's suddenly sent off on staff assignment to Europe, where he is soon immersed in the cynical swirl of Old World politics. Wake finds himself running for his life after getting embroiled in a Spanish civil war. Then he gets caught up in diplomatic intrigue among the French, Germans, and British. But his real test comes when he and his old friend Sean Rork are sent on a no-win mission in northern Africa.
