Poirot goes to a hostel where students stay in England that are going to school there. Miss Lemon's sister runs the hostel. She is upset because things are being stolen from the students and the police are getting involved.
There are many characters in this episode most of them are students that live in the hostel. A suspicious man watches as people arrive in England There are students that are in the medical field, history and also clothes designing.
Poirot invited Japp to stay with him for a week an Poirot makes his favorite meals for Japp to enjoy (which are strange and Japp does not like). Japp does not know what a bidet is that is in the toilet at Poirot's and tells Poirot he wet himself with it. Poirot is embarrassed and does not want to explain what it is especially in front of Miss Lemon.
There are more mysteries in this. Stealing. murder and the connection between them and a business that sells heavy bags to carry books etc.
At the end Inspector Japp invites Poirot to eat over and he makes him "English" meal with three things and dessert. The meal is mash potatoes, mushy peas, and "faggots" (bits of pork and mixed meat). For dessert he has "Spotted Dick" (pudding. The meal scene is funny. Poirot says he has a "allergy of the faggot". Japp is disappointed and says "you haven't got a phobia to dick have you?" referring to the pudding.
Suspenseful and funny.
