Thanks Jo,
I found some detail in the Chester Courant (on microfilm at the Chester History and Heritage Centre) at lunchtime today.
I then rang Flintshire RO who referred me to Denbighshire who confirmed they do have the inquests / coroners records for 1927 but the 100 year rule applies.
I then rang the Coroners Office in Wrexham who said if I apply to them in writing, they may grant permission for me to go to Denbighshire and view the record. However, if I want a copy of it then the Record Office have to send it back to the Coroners Office to copy and a fee would probably be payable.
I'll email the Coroners office tomorrow and start the ball rolling ....
