Brief Re-Encounter

Miss Courtney is delighted when Albert Collins, the man she was supposed to marry 25 years ago but lost contact with, comes back into her life. He asks her to wed and she agrees, but he suggests that as his money is tied up abroad, she should lend him the money for the ceremony. When Sid tells him that Albert is a notorious confidence trickster, Mr Brown and the students come to Miss Courtney's aid.
