"There's no need to be so harsh,"

Mori had written, in response to one of Dazai's less-than respectful comments,

"the fruits of our labors will reveal themselves shortly."

The letter had arrive just that morning. In fact, Featherbrain's awful hooting had woken Dazai up when she'd arrived. He'd startled, sitting up wide-eyed and throwing his blanket to the floor, only to find the owl preening, self-satisfied, on the sofa's armrest. She'd promptly dropped the letter in his lap. The only good thing about the whole situation was that Featherbrain had gifted him one of Mori's really fancy pens 'the kind that Dazai knew she must have pilfered. Mori was probably fuming over the loss. That thought made Dazai smile, so he hadn't scolded Featherbrain to hard.

Still.

The fruits of our labors...

Dazai had read that line over three times before finally burning the letter up with an incendio. No evidence left behind ever again.
