Kunikida is being held for a murder that Rampo is certain he didn't commit. Meanwhile, Poe is determined to solve a murder mystery that has had the poilce stumped. Rampo has some thoughts on that situation, too.
The evidence destroyer himself shoved 
the victim down to cover his tracks.
.قام متلف الأدلّة بدفع الضحيّة بنفسه لإخفاء آثاره
Der wahre Beweismittelzerstörer
warf ihn zur Tarnung herunter.
… que l’effaceur a tué cet homme
afin de simuler sa propre mort.
Lo stesso distruttore di prove ha spinto giù
la vittima per coprire le proprie tracce.
O próprio destruidor de evidências
empurrou a vítima para cobrir seus rastros.
Стиратель улик столкнул жертву,
чтобы выдать её за себя.
