A string of bvurglaries that take place at night, and where the thieves leave no trace make for a baffling case for Joe Friday. He and Frank Smith go to talk with the witness about her security measures. The Burglar alarm was set, locks locked, safe secured, but the robber got away with the goods anyway.
Who is Alan? He’s not an employee, but should he be trusted with having run of the place? In this theft, and other burglaries alarms have been bypassed, entry is through locked doors that are relocked, and left unmolested other than goods being taken. Could it be an inside job? Where is the common thread between all the various robberies?
The cops think they have enough to set out a stakeout, but will their diligence pay off for them? How was the robber able to crack into the stores and bypass the security measures? Ride this case to the end for those answers.
