Terror at the Soo Locks

TERROR AT THE SOO LOCKS is an old-fashioned mystery filled with suspense, foreign intrigue, and romance. A foreign freighter is blown up in the Poe Lock...

Why?

Is it to sabotage the flow of iron ore through the busiest shipping system in the world? Is it to kill an international crime fighter, or to kill a professor who knows the mysterious Singapore Girl?

Lewis takes the reader on a suspense-filled adventure in the Upper Peninsula of Michigan
