Liked it a lot!
Death in the clouds
The seven dials mystery
Understood Betsy

Liked it
Mr. Parker Pyne, detective
All-of-a-kind family
The Saturdays
The year of Miss Agnes

OK
The war with Grandpa
Tales of terror from the tunnel's mouth

Didn't like it
The sword in the tree
Utterly me, Clarice Bean
The monsters of Morley Manor
