Meanwhile, the other children have stolen a scarlet fever quarantine sign and posted it on the bachelor's door. The police, unaware that the quarentine sign is a prank, enforce the confinement. But aided by the sweet disposition of the toddler quarantined with them, the icy relations between spinster and bachelor begin to thaw, . . .
