A Shadow in the Den An uncertain sight Jupiter Jones sees movement near the bookshelves and briefly thinks Pete Crenshaw is in the room. Pete is actually elsewhere, leaving the sight unexplained. Perception tested Jupiter calls it a shadow, but does not forget it. The scene introduces a distinction between what someone sees and what that sight proves.

A Locked Church A Locked Church from "The Mystery of The Invisible Dog". A Locked Church A frightening encounter Jupiter Jones sees a candle-bearing figure and is then attacked and locked inside St Jude’s Church.

A Locked Church A frightening encounter Jupiter Jones sees a candle-bearing figure and is then attacked and locked inside St Jude’s Church. The experience combines a visual mystery with a demonstrable crime. Witnesses disagree Father McGovern denies that a priest was present, while Mrs O’Reilly believes in a ghost. Conflicting testimony makes certainty difficult even before the boys investigate further.

Limits admitted Lantine cannot prove that Elmquist has the ability, and she has no evidence that the church ghost exists. Expertise expands possible explanations without ending uncertainty.

A Physical Test Contact made visible The black marks on Prentice’s desk demonstrate that a visitor handled the drawers. The result is stronger than speculation because another person can inspect it. Calibrated belief The experiment proves Mrs Bortz entered, not that all the haunting reports are false. Evidence resolves a limited question rather than every mystery at once.

No Final Ghost Proof No Final Ghost Proof from "The Mystery of The Invisible Dog". No Final Ghost Proof Explanations remain plural Jupiter Jones lists several ways the phantom priest might have appeared, each with a difficulty.

No Final Ghost Proof Explanations remain plural Jupiter Jones lists several ways the phantom priest might have appeared, each with a difficulty. The boys cannot make the evidence fit a single complete account. Intellectual honesty They leave open the possibility of a ghost without claiming certainty. The ending values disciplined doubt as much as the successful identification of Murphy.
