Look to the Lady (apa
The Gyrth Chalice Mystery) is the third in the Albert Campion series by Margery Allingham. It is a US Kindle Countdown deal at $0.99 for about 1 1/2 more days. The e-book publisher of these in the US, Ipso, seems to be rotating them through Countdown, but only for a very short time for each one, so grab it fast if you want it. (Note the Ipso titles are only $3.99 not on sale anyway, which is IMO a reasonable price - although the upper edge of my idea of a reasonable price - for classic/famous backlist....)
Also, be cautious - this is one of the titles in the
Margery Allingham Box Set 1 that was on sale a while back, so if you bought that, you already have this.
And finally, BTW, the link at the end of the blurb for the "previously unpublished Allingham story" is legit, as discussed
upthread, and signing up for the newsletter has not gotten me flooded with emails, I only remember two? or three?
