Death before Wicket (Phryne Fisher Series #10)

Phryne Fisher has plans for her Sydney sojourn—a few days at the Test cricket, a little sightseeing and the Artist’s Ball with an up-and-coming young modernist. But these plans begin to go awry when Phryne’s maid discovers her thoroughly respectable sister has left her family for the murky nightlife of the Cross. And Phryne is definitely not the woman to say "no" when two delightful young men come to her on bended knees, begging for her help in finding their friend innocent of theft.

It all sounds simple enough as Phryne sets investigations into motion, but when greed and fear are the motivating factors, people become ruthless and Phryne finds herself enmeshed in blackmail, secrets, lies and the dangerous influences of deep magic.
