I've been reading an extraordinary amount of murder in the bath the last few days. I haven't reached any startling critical conclusions - beyond
1) Margery Allingham always remarkable.
2) Edmund Crispin brilliant, but sometimes pointless
3) Dorothy L Sayers very literary, but not that interested in variety of suspects
4) When Agatha Christie is good, she's unbeatable. When she's bad, she's puzzling.
Also read "Who Killed Roger Ackroyd?" a remarkable French critical text that argues convincingly that it wasn't who you'd think.
I tried reading Anthony Trollope, but 75 pages into Phineas Finn and no corpse. Fail.
