For this blog alone — that is, discounting books I manage to fit in which do not feature on here — my reading has in recent weeks seen a degree of decade-hopping it doesn’t normally achieve: 1971, 1948, 2011, 1938, 2018, 1940, 1939, 2018 and now 1932. The upshot of this time travel is a reassurance that I’m still more of a fan of the legitimate 1930s style of murder mystery than I am its more modern second cousin. Even the flaws in this type of story are more enjoyable, partly I suppose because (and it bears repeating) of just how damn difficult a well-clewed puzzle plot is to write. As here, the first swing often makes up in enthusiasm for what it lacks in finesse.
