Sir – On Friday, September 30, I visited Oxford for the afternoon and unfortunately was taken ill because of the excessive heat.

I was at a service in Christ Church and the Red Cross people who first attended me there, then the paramedics, one of whom took myself and my friend to the John Radcliffe Hospital, were wonderful. Once at the hospital, I was treated extremely well.

When we were ready to leave, at about 11pm, the staff, (the doctor who had seen me and a gentleman, I think, not on the medical staff) really put themselves out, well beyond the call of duty, to find us a hotel room.

There are no words to express how grateful we are to them. Unfortunately, I don’t remember the names of any of these good folk but if they read this, they will know who they are.
