The Volunteers in Room Nine, a psychological thriller concept package. The graphic shows 3 novel covers and the free lead magnet, The Chair Marked Spare.

The concept

A city offers paid days off for people volunteering in harmless public research. At three different follow-up meetings, a volunteer discovers that somebody outside the study has used its rituals to reshape a personal decision. A coloured envelope or a roomful of raised hands begins as reassurance and becomes the reason a woman doubts what she knows.

Maggie writes her answer, seals it and forgets it. At a family dinner a stranger repeats the sentence, including a word she crossed out before sealing the green envelope. The free companion novella is The Chair Marked Spare.

The worldIndependent participants, different studies and a returning former volunteer, Nina Fordham. Consent can be withdrawn. Every disturbing action has a human motive outside the legitimate research. A participant conceals a connection, a name or the role they really came to play in each case.

Series tropesSecret Identity • Underdog • Opposing Morals to Moral Growth

Intended readershipFor adult readers who enjoy social pressure, moral discomfort and reality that can be checked against a physical record.

Tone & contentIntimidation and brief physical peril. Participation, memory and vulnerability are treated with respect.

The Chair Marked Spare

One chair is marked spare. By lunch all twelve volunteers remember somebody sitting in it. Nina and Gus compare their descriptions and realise they have described each other’s coats.

Story outline

The Answer in the Green Envelope

Maggie writes her answer, seals it and forgets it. At a family dinner a stranger repeats the sentence, including a word she crossed out before sealing the green envelope.

Story outline

Story arc and endingHer brother’s lover worked the dinner and intercepted a returned envelope to discover whether Maggie witnessed an assault. A fluorescent thumbprint is simply the green chalk used by a volunteer painter, an innocent source. The true clue is the menu padding cut from the envelope’s distinctive flap. Maggie and Sanjay trace it to the diner who sent threats. They turn the evidence over and meet again on their own terms.

Emotional payoffMaggie claims the right to speak when she is ready; her tentative romance survives the pressure.

Everyone Raised a Hand

Everybody raises a hand to say the man in the picture struck first. Suzie is the only holdout, until Adam squeezes her sleeve. At home she remembers the blow with absolute clarity.

Story outline

Story arc and endingThe clip stopped before any blow. A participant rehearsed several accomplices to discredit the man who reported his earlier abuse. Suzie notices the shadow of a clock never advances. Adam admits he followed the crowd. Their independent requests for the original film prevent further coaching. The threatened man is warned and the instigator’s written invitations settle his role. Suzie and Adam start seeing each other after both give statements.

Emotional payoffThey accept that supporting someone sometimes means disagreeing in a roomful of raised hands.

The Volunteer Who Wouldn't Leave

Everyone is told the follow-up is over. A man remains by the only exit asking each woman what her partner fears. Lesley notices he never takes off his visitor badge.

Story outline

Story arc and endingThe man is a former participant posing as a researcher to locate an ex who used the group to rebuild friendships. Lesley had given him a real detail out of politeness. She and Harry contact the research office independently, move the women to a staffed public room and call police when he follows. Visitor records and unanswered consent forms corroborate the impersonation. Lesley later chooses Harry as a partner who welcomes a direct no.

Emotional payoffShe stops treating compliance as proof that she is healed.
