He was a hardboiled lone-wolf investigator whose real name was never revealed. And he was a true company man, identified only by the name of the business he worked for, with an "Op" tagged at the end. His stories were tough and violent, and while they sometimes revealed him to be indecorous or not particularly heroic, he laid them all out in a straightforward, first-person style. He was, however, not the Continental Op. Credited as the author was the mysterious "Jan Dana," in reality John Lawrence: a former stockbroker and author of another long-running Dime Detective series, the Marquis of Broadway. Volume 1 collects the first six stories in the series. Includes an all-new introduction by John Wooley.
