A/N: This was just sitting there, begging to be written.
'Let's call a spade a spade, you kissed me.'
'You kissed back.'
'And I'm not here to apologise.'
There was a moment of tense, tangible proximity before Mrs Prout burst in the door followed by Cpl. Collins, valiantly attempting to usher and announce her from behind.
'Then why are you here? To drape yourself all over my crime scene and make trouble! You're going home. Excuse me Collins, Mrs Prout, this will only take a moment.' The Detective Inspector took Phryne by the arm dragged her out of the office while she objected with passion but not success. He just walked on silently. She was at the point of repeatedly hitting his arm with her free one by the time they got to the stairs. They were out of earshot, so while descending the wide staircase Jack spoke.
'Go home...'
'I won't...'
'Phryne! This has got out of hand. Walls have ears and I can't have you distracting me on a crime scene. Go home... Have a bath. Don't get dressed. I'll be there by midday with everything I've found. And if you promise to be less... More... ...Professional, you can come back here tomorrow.'
They shared a quick, passionate, dirty kiss halfway down the stairs before turning their separate ways, determined to be professional.
Until midday.
