SERGEANT SPOOK had a most tragic origin – he died. Caught in a lab explosion when his pipe was too close to dangerous chemicals, Sergeant Spook could only be seen and heard by teenager Jerry. Don't worry, though – Sgt. Spook could still land a good punch! Together Sgt. Spook and Jerry, assisted by Dr. Sherlock, fought crime wherever it might be found. His adventures took some twists and turns, so don't think this is your average ghost detective series! SERGEANT SPOOK appeared in 100 issues of Blue Bolt Comics --- and here they are in three great volumes! This book contains the stories from Blue Bolt #1-33 (June 1940 – December 1942).
