You mean the Case Of The Expired Parking Meter? Where Our Hero barely made it to the meter ahead of the parking meter ticket lady?

Or perhaps you refer to The Sordid Story Of Stolen Romance, where he managed to stop a woman who was leaving the store and had forgotten to pay for her "True Romances" magazine?

Or the Case Of The Empty Cigar Box, in which he found that he'd smoked his last cigar and had to go by a new box?

Or the Adventure Of The Evicted Tenant, where he couldn't pay his rent and got tossed out on the street?
