Yesterday, Graham Norton interviewed JK Rowling / Robert Galbraith regarding Lethal White on BBC Radio (you can listen to the interview here at https://www.bbc.co.uk/radio/play/m0000n1w starts at 2:26:00 onwards). Just before Norton introduces JK Rowling, they play this song called "One Strike" (2016) by girlgroup All Saints.

I thought of course they use this song because of the title. The song is pretty catchy and I looked it up on the internet. It turned out that the song was inspired by the breakdown of the group member Nicole due to her divorce from singer Liam Gallagher. It kinda parallels with Robin's situation in this chapter isn't it?
Then I looked up the lyrics, I decided that this could be Robin's love life song. With the 'one strike' could also mean a Cormoran 'Strike' :

Stone cold
You wake me when the phone vibrates
Your voice sounds dulled, but loud enough to hear you
Distant, echoes of my heart unbreak
Silently now, I'm waiting for this storm to come
I'm waiting for this this storm to come
Listen to you load that gun
I'm waiting for this storm to come

(Reff) And with one strike
My world lights up in a fire
Call it a sign
Don't need hindsight
I'll make my emotions clear
And then disappear
With one strike (one strike)
Mmm, one strike

Shattered, pieces of your words take aim
Your poisoned tongue
But I don't want to believe you (don't want to believe you, don't want to believe you)
Torn up, stitches of my own heart ache
Violently numb, I'm ready for this storm to come
I'm ready for the storm to come
Listen to you load that gun
I'm ready for the storm to come

Reff

I don't want to stay, time to go
I don't want to be in this home
Broken promises, time to leave
I had everything that you needed
I don't want to stay, time to go
I don't want to be in this home
Broken promises, time to leave
I had everything that you needed

(Reff)

Oh-oh
Why'd you go lie?
Oh-oh
Why, oh, why?
Oh-oh
Watch you go by
Oh-oh
My, oh, my  

I've been listening to the interview on Saturday, herad the song for the first time then. Good call! Totally fits.
