Interesting as an attempt at a new type of detectiving person but mostly pulpily written. Nevertheless not a bad read.
I was a bit disappointed when the detective found out the way Nita was murdered because the plot went so well until then. Anyway, this novel will keep you hooked until the end.
Poul Anderson is one of the best SF authors, one who always knows his tech background. This novelette shows his skills in constructing an asteroid belt station with all the details. Of course, the story is standard pulp but who cares.
While his writing is nearly as cryptic as Chesterton the author's stories have more down to earth subjects. Result is a collection of master thief shorts set in 1910's New York that each give you food for imagination and some thought afterwards. Definitely not pulp.
