I have read 4 Tey novels and just the 1 Allingham.

So, for Tey i really liked all of them, but To Love and be Wise and The Franchise Affair were my favourites. Daughter of Time is another famous one, but i haven't read it yet. (The other two that i did read were A Schilling for Candles and Miss Pym Disposes )

The only Allingham i ever read was Hide my Eyes . I quite liked it, because you already know who the killer is right in the beginning, but it's all about when and how the story will resolve itself.
