Honor Bound - Robert N. Macomber - Bog

In this eighth novel in the Honor series of naval historical fiction, it's June 1888 and Commander Peter Wake, U.S. naval intelligence agent, is in Florida leading an espionage mission to learn Spain's naval readiness in Cuba. A woman from his past shows up, begging him to find her missing son, and Wake sets off across Florida, through the Bahamian islands, and deep into the dank jungles of Haiti. Overcoming storms, mutiny, and shipwreck, Wake discovers the hidden lair of an anarchist group planning to wreak havoc around the world-unless he stops them.
