Martin Edwards will be speaking at the conference on the works of Richard Hull. To get you in the right frame of mind for this you might want to check out the following books:
The Murder of My Aunt by Richard Hull
Blood on the Tracks by Martin Edwards
Bats in the Belfry by E. C. R. Lorac
I might add that I am currently reading Murder Isn’t Easy by Richard Hull, which has a similar tone to The Murder of My Aunt. It also promises to be every bit as good as, and as convention-upsetting, as that novel.
