Sign in

''Almost everyone remained silent or lied during the subsequent investigation. All of them signed an oath of silence in their own blood moments after witnessing the horrific crime in a ceremony staged by the murderers.'' www.thefirstnews.com

I understand a context of this and I know that the oath was signed with blood, but it is common to use 'in' in such a situation?

Thanks

Signed pencil, ink, blood, etc. seems normal to me, Fragers.

Nice to know, thanks as usual!
