Tombful of Trouble - Session 7 - Reading Comprehension answers

In Session 7 of "Tombful of Trouble", Agatha and Christie astutely discern that the artefacts in the store are counterfeit by noting the alabaster vases' suspiciously light weight and their identical nature. Mr. Russell is deeply distressed upon this discovery because he has mistakenly sold these forgeries to an American buyer as authentic, fearing the buyer's reaction to being deceived. Agatha deduces Ada's involvement through her particular set of skills, which include sleight of hand and maintaining an air of innocence. Ada's letter is found, serving to elucidate her actions and motivations. The method of Ada's entry into Mr. Russell's storeroom is revealed to be her adept lock-picking. The phrase 'it was just a hunch' is interpreted as having an intuitive feeling about a situation, without concrete evidence to support it.

A concise summary of the session could encapsulate the key events: Agatha and Christie uncover fakes in the storeroom, leading to Mr. Russell's dismay over selling them as genuine. Agatha suspects Ada, who confesses in a letter and is revealed to have picked the storeroom lock, all based on a mere hunch.
