‘The Portugal Sapphire’ (2013) by J. A. Jernay

Meta-data from GoodReads is 3.13/5 from 114 litizens.
Verdict: First in a series and last for me.
In these pages our heroine
Port sapphire.jpg
– Learns conversational Portuguese in ten days
– Has hormone attacks at the appearance of any man with hair and teeth
– Starts with USD 2000 and all expenses paid and yet is broke on every page thereafter
– Trusts known criminals 
– Is too naive to have made it to 29 years of age
– Flies from SFO to Lisbon in 3 hours
– Repeats the same dialogue far too often
– Cracks a long established Lisbon crime syndicate in one afternoon
– Out muscles experienced villains
– Whose legendary knowledge of gemmology is never revealed or relevant
– Who talks her way past alert criminals
– Leaves her handbag in the villains lair and has to go back for it
– Passes off an offsider as blind on a guided tour
– Does IKEA in each room
– Does Vogue with the dress of each woman and GQ for most men
– Almost none of the detail that plumps out the pages adds to plot or character
– Characters who are emphasised disappear like the police sergeant who did not collect
And so on.
Rom-krimi or Krimi-Rom is this genre bender. One in a series of many titles. First and last for me.
I came across it looking for novels set in Portugal before travelling there. No more for this reader. Though it is claimed to be a best seller in a heavily qualified attribution, among self published mysteries on Tuesday.
The prose is fluent and confident but absent either plot or character. There is some travelogue in Portugal but it is obscured by the features listed above.
