Each story was recounted in flashback, and every few minutes the action would be interrupted by Johnny listing a line item from his expense account, which served as an effective scene transition. Most of the expense account related to transportation, lodging, and meals, but no incidental expense was too small for Johnny to itemize, as in "Item nine, 10 cents. Aspirin. I needed them." The monetary amounts weren't always literal: the smallest line item Johnny ever recorded was "two cents: what I felt like" after a professional setback; the largest was "one million dollars" (the way he felt after finding a missing woman and her daughter in a snowbound cabin). The episodes generally finished with Johnny tallying up his expense account and traveling back to Hartford, Connecticut, where he was based. Sometimes Johnny would add a sardonic postscript under "Remarks," detailing the aftermath of the case. ("The Todd Matter," which especially disgusted Johnny, ended abruptly with "Remarks – "nil!"")
