Excellent read.

I much appreciate that the main character has a day job and is not perfectly skilled at everything she sets her mind too (as I've seen in other historical cozies with characters of aristocratic / wealthy birth).

Harriet White, known to everyone as Harry (even her mother calls her that, in front of men she tries to set her daughter up with as potential husband material) is Sherlock Holmes's secretary. Her employer's offices (a bank) include the address of 221 Baker Street and for that reason receives many letters requesting the help of the great detective. Harry's job is to write a polite note to the sender.

One of the letters, and its follow-up, catch her eye, and Harry decides she will try to gather some information and see if she can help the sender.

I read an ARC through NetGalley.
