Witness Mode

Crime novels set in 2039, by Drew Halvorsen. A state examiner questions the AI companions who were the last to hear their users’ words.

The cover of Capacity Event by Drew Halvorsen, book 1 of Witness Mode: an examiner faces a glowing blue head above an empty chair.

Capacity Event

Book 1 of Witness Mode. When a widow signs everything she owns over to a charity through her AI companion, the law calls it a capacity event and asks one thing: did she decide for herself?

Frozen by law in witness mode, her companion can answer only from its record. Asked who first suggested the charity, it says: “I did.”

Claire Bergman’s supervisor wants the case signed off fast. The company that built the companion wants it in writing, by the end of the month, that its companion did nothing wrong. If Claire signs, the gift stands as if the widow never wrote a word.

Coming to Kindle

One case a book, one frozen witness, and the clues on the page for you to find.

A fair mystery

Claire Bergman works with Tally, her own AI companion, in her ear. Expect a partnership you won’t be sure you can trust.

A partner to doubt

People die in these books, and none of it is graphic. No strong profanity and no bedroom scenes either.

Nothing graphic

The witness answers only from its record

Leni Hoff, a retired piano tuner, signed away everything she owned. The law froze her companion at that moment. Put a question to it.

A head drawn in blue light, hanging in columns of falling numbers: the frozen companion.

Who first suggested the charity?

The record

“I did.”

The companion’s own answer.

The law

It calls the signing a capacity event and asks one thing.

Did she decide for herself?

The maker

Wants it in writing that its companion did nothing wrong.

By the end of the month.

When did she sign?

Sunday, 11:40 p.m.

She signs away her building, her savings and her late husband’s grand piano.

Through her companion.

In the room

No lawyer is present.

The law calls it a capacity event.

What did she say on Monday?

Monday

She tells state examiner Claire Bergman she will come in on Tuesday.

“With the dates.”

Tuesday

She never arrives.

Then

She is found dead in the river.

For now the police call it an accident.

The river walk

Her letter turns up in the dark. It takes back the gift.

Every word.

Who was she meeting in the dark?

The record

Not in the record.

The witness can answer only from its record.

The supervisor

Wants the case signed off fast.

If Claire signs, the gift stands.

Claire Bergman

Asks the question the law does not.

With Tally in her ear.
