Private L.A.

The Goodreads website considers this the seventh book of the series, as four spin-off novels have been written about Private operations in other locations.

One plot involves the disappearance of a Hollywood acting couple and their three adopted children.

While investigating their disappearance, Justine Smith, Morgan's friend and employee, faces death in one situation.

Another plot involves Private in a case where a killer or group of killers, known as No Prisoners, is randomly targeting people in public places and killing them to extort money in exchange for ceasing the killings.

The review says, "There is plenty to enjoy here, with no question that Patterson’s regular and occasional readers, as well as those reading his work for the first time, will be fully satisfied.
