"Allan's Wife" H.R. Rider-Haggard
Not as objectionable as the Bulldog Drummond series (or at least, those of that that I've read) but still quite old fashioned in its attitudes. Nonetheless, I'm enjoying the Allan Quatermain series, attempting to read them in the chronological order suggested
here. So far, they've rattled along in fine style, and are exciting and enjoyable enough that I find I can overlook their Imperial era outlook on the world.
"The Art of Capataincy"
Very readable book by Mike Brearley about cricket captaincy - some lovely anecdotes, and very readable, despite my being about as likely to captain a cricket team as I am to have the sort of adventure that Mr. Quatermain does.
"The Junkyard Dog" Robert Campbell
I love Robert Campbell's "Whistler" series, and wish that they were easier to get hold of. This book is the start of his Jimmy Flannery series, and so far has the charm and dry wit of the "Whistler" books. If you have a Kindle, this book was free when I got it, and the others appear to be available through the lending library.
