I will review each novel in this omnibus immediately after reading and will update the review accordingly.
The House Without a Key:- the first appearance of Charlie Chan dates from 1925 but reads better than many mysteries of that period. The writing is surprisingly good and the impact of Hawaii on "outsiders" is vividly conveyed. There are red herring in plenty, and a fair quota of romance, which is par for the era. The characterisation and plotting are solid, although I spotted the perpetrator without too much difficulty. This was both interesting and very readable.****
