'Thrilling and perilous adventures' NEW YORK TIMES
Captain Duncan Maclain was blinded during his service in the first World War. Now he is one of New York City's most sought-after detectives, achieving a mastery of the subtle unseen clues often missed by those who see only with their eyes.
Now, with the outbreak of a second world war, Maclain is pulled into a case unlike any he's investigated before. Aided by his dogs Schnucke and Driest, the Captain puts the intelligence-gathering techniques he learned in the Army to work on a case involving German spies, where it is almost impossible to tell whose side anyone is on.
