Explanation:

1. Reporting Verb and Clause:
The conversion into indirect speech is initiated by using the reporting verb 'said'. The reporting verb is used to indicate that the statement is being reported from the intruder to another person. The reporting verb is followed by a reporting clause that introduces the speaker and provides information about when and where the statement was made.

2. Statement in Indirect Speech:
The intruder's statement is transformed into indirect speech by changing the pronouns and tenses accordingly. The first-person pronoun 'my' is changed to 'his' to reflect the intruder's perspective. The present tense verb 'is' is changed to 'was' to indicate that the statement was made in the past. Similarly, 'will' is changed to 'would' to reflect the conditional nature of the statement.

3. Retaining the Meaning:
While converting the statement into indirect speech, it is important to retain the meaning and intent of the original statement. The focus should be on accurately reporting what the intruder said without adding or omitting any crucial information.

4. Additional Information:
In the conversion, the intruder's statement is divided into two sentences for clarity. The first sentence states the intruder's specialty as jewel robbery and the second sentence mentions that the car would be suitable for his plan. The additional information about the car being a 'dandy bus' is also included in the reporting of the statement.

Overall, the conversion into indirect speech accurately reflects the intruder's statements while following the rules of grammar and tense usage.
