A woman alone

"A woman traveling alone makes nothing but trouble." Captain Neil Macklin's firm opinion was reinforced when Miss Audrey Bracewell, from the Fairmead Nursing Home, was late to join his ship for a convalescent cruise. But what Captain Neil did not know was that, when his overdue passenger arrived, it was not Audrey at all but a night nurse from the Fairmead -- Jane Lester. Captain Neil was not pleased when he found out, but was it not possible for Jane -- with no doctor aboard and she the only nurse -- to prove to Neil, if an emergency developed, that she could mean the reverse of "trouble"?
