Kobo South Africa has two of Tasha Alexander's Lady Emily series short stories for R24.15 (+ tax of 3.38, total R27.53). So that's AUD2.28, and probably under USD2.
Star of the East (2014)
Blurb:
Spoiler:
Emily and Colin Hargreaves make it a rule to spend as little time as possible with her parents in Kent, but are unable to refuse Lady Catherine Bromley's invitation to join them for a pre-Christmas party that includes the family of Ala Kapur Singh, a powerful Punjabi maharaja who has come to England after receiving the Order of the Star of India.
Lady Bromley, quite taken with the exotic beauty and spectacular jewels of the maharani and her daughter, Sunita, throws herself with abandon into her own version of Indian culture, planning a feast she is certain will be more spectacular than any seen on the sub-continent.
When a priceless diamond maang tika and a simple gold bangle disappear from Sunita's room, a diplomatic incident seems imminent, particularly after the maang tika turns up in Emily's possession.
Emily may have what appears to be the more valuable of the two pieces, but the maang tika cannot be worn without the bangle, upon which is engraved the words necessary to ward off a curse placed on the set five hundred years ago by a princess forced to forsake the man she loved.
Sunita must wear the maang tika at her wedding but cannot do so without the bangle. Can Emily convince the maharaja that she is not a thief? And, more important, can she and Colin find the bangle?
That Silent Night (2015)
blurb:
Spoiler:
In this new short story from Tasha Alexander, Lady Emily and her dashing husband Colin are spending a few days in London, doing some last-minute Christmas shopping and making the most of the time alone, when they find themselves in the middle of an unexpected mystery.
The couple is just getting cozy, not at all bothered by the storm outside. But when Lady Emily looks out the window to see a woman standing in the blowing snow, without a coat, an eerie feeling falls over her, and she rushes out to help, only to find that the woman has disappeared.
Colin is convinced her eyes were playing tricks on her, but Emily is haunted by the woman's image. Clearly, there is something spooky afoot, and she is determined to get to the bottom of it. . . .
Edit
I've just realised that both these short stories are also at Kobo US & CA for USD1.99 and CAD1.99
Edit 2
Both these short stories are EPUB3 if that is of concern to anyone.
