You have a wrong letter in 6d. The answer is BAIL OUT.

BA+I+LOUT

10d STRESSES (Mistresses - I'm)

19d See the s

19a Striking ?

4a SHRUB

Sh rub

[merlinius]

Or even "smashing" maybe!!

[Rollo]

Presumably 19a and 19d start with the same letter.

So I reckon 19a starts with an S - I like STRIKING, it answers the clue nicely.

[merlinius]

19d is "see the s"

[mazie]

I was thinking along the lines of Striking a record (the making of old vinyl records) but my memory could be playing tricks!

[merlinius]

19a Could be either depending on what the 4th letter is!!
